The F-gas Regulation aims to reduce F-gas emissions by two thirds of 2010 levels by 2030, by improving the leak-tightness of equipment, promoting the use of more environmentally friendly alternatives to F-gases and capping sales of HFCs on the EU market through an HFC phase-down. HFC target limits are already in place in Europe which has a dramatic effect on global manufacturers and the phase out of R410A has already started. HFC EU limits for single split air conditioning (<3kg of F-gases) is GWP = 750 by the year 2025.
*Based on the Kigali Amendment to the Montreal Protocol ratified in October 2019. Ministry for the Environment. 2017. 7. Wellington: Ministry for the Environment.
As a result of this phasedown, we are seeing refrigerants with lower GWP (in particular R32) in many air conditioners and hot water heat pumps. It won’t stop there, that’s just the interim refrigerant before moving to natural gases, including some controversial flammable gases such as Propane.
We do have an option that is here already, CO2 refrigerant. It is a natural gas. It is what we breathe out into the atmosphere and it's what feeds plants to grow. CO2 can also be used as a naturally occurring, non-flammable and stable refrigerant fluid solution for hot water heat pumps.
It is non-toxic (at reasonable concentrations) and with a Global Warming Potential (GWP) of 1, it is also the base refrigerant that all other refrigerants GWP numbers are based on and will future-proof the way homes and businesses heat water.
It's a progressive move for most manufacturers to change refrigerant to a lower GWP - Mitsubishi Electric has already begun to take the lead with hot water heat pumps utilising CO2 refrigerant.
The QUHZ Ecodan is an advanced hot water heat pump that can provide both domestic hot water as well as supply hydronic space heating through radiators or underfloor heating.
Utilising CO2 as a natural refrigerant, it is the number one environmental choice for domestic hot water heating and an alternative to gas and direct electric systems.
The Ecodan QUHZ Hot Water Heat Pump is revolutionising central heating and domestic hot water technology in New Zealand.
With space often being a premium on new build development sites, Ecodan QUHZ will operate discreetly where dwellings are in close proximity to each other. The QUHZ Outdoor unit provides very quiet operation as low as 43dBA (SPL).*2
Specific outdoor unit design features enable quiet operation to be maintained in all modes of operation and all ambient conditions as well as allows improved flexibility for the installation locations. The Ecodan QUHZ will help residential areas that are particularly sensitive to outdoor noise to benefit from renewable heating technology.
Not only is the outdoor unit quiet, the compact indoor cylinder provides the equivalent of 250L of hot water using plate heat exchanger technology drawing heat from the 200L thermal store. Separated from the stored water, instant production of hot water means there is no risk of legionella while achieving up to 70°C domestic hot water.
In addition, the QUHZ can heat the whole home easily with temperatures up to 60°C for radiators or underfloor heating. With combined domestic hot water, the QUHZ is the low carbon footprint option for new homes. By future proofing and adding value to the property, it is the number one choice for developers, architects and builders alike.
There’s usually an argument to say that heat pumps can’t produce the higher temperatures that gas boilers can achieve, but with CO2 refrigerant, temperatures up to 90°C can be produced in ambient outdoor temperatures as low as -25°C.
The high discharge temperature from compressing the CO2 gas means we can now achieve high temperatures and achieve high efficiency because the CO2 refrigeration cycle works best with a large temperature difference. For sanitary hot water production this technology is the way forward, to be able to reach high temperatures for wash downs, leisure facilities, potable hot water and for the industry to seriously meet carbon reduction targets. QAHV is certainly the solution.
We will see more CO2 hot water heating products in the future and these products will no doubt become the norm for generating potable hot water and efficiently heating our homes.

Creating a healthy environment is important when renovating or building a new home. Your customers will value your advice and expertise in all aspects of ventilation. Make this your competitive advantage and share the following 6 tips with them, to ensure they invest in the best ventilation solution for their health and home.
It can be easy for homeowners to jump straight into the design aspect of planning, however this can often be the first mistake made. Too often people consider ventilation once their build is in progress or even complete and find their plans make installation difficult, more costly and often result in a make do application that isn't what they were initially after.
By bringing in a ventilation expert in the early planning stages you can save future headaches. Always ensure a ventilation system is integrated into plans to maximise efficiencies. Ducted air conditioning with combined Lossnay Ventilation is a perfect example of something that is best to bring in an expert early in the process for. Installation, ducting and wiring is far easier to manage before the ceiling is put in place, allows flexibility with outlet placement and Lossnay's heat recovery will add further efficiency to the air conditioner when in operation.
Ventilating our indoor spaces is more important than ever, but they should also be as energy efficient as possible.
Mitsubishi Electric's unique heat recovery technology recovers up to 85% of the heat energy from the outgoing stale air which is then used to pre-warm (or pre-cool) incoming fresh air. Why not take that warm air from the sunniest side of the house to pre-warm the outdoor air being filtered in? Or use the air you have already paid for to heat.
Heat recovery means any heating or cooling appliance does not have to work as hard to reach the desired room temperature – providing savings on energy bills.
Placement of ducts and grilles are almost as important as the system behind it.
Often ventilation systems are not working as efficiently as possible because they are drawing air from the coldest parts of the home and not taking advantage of those areas which are naturally warmer. It goes back to heat recovery, the best thing you can do is make use of that free energy.
To achieve compliance with the Ventilation Standard NZS4303:1990 of the New Zealand Building Code, a building's ventilation system is required to draw fresh air from the outside in order to achieve acceptable indoor air quality.
Not all air is created equal. The absence of significant air movement common in attics means the air is likely to be stale. In addition, build-up of dust, dirt and other contaminants such as mould, insect and rodent droppings makes this air much harder to filter before it is distributed through your home - it's not what you want to be breathing in.
All products in our Lossnay Ventilation Range draw fresh air from outside and filter this to maximise air quality. While systems that draw from the roof are less common since the standard was introduced, these systems can still be found in the market to target those wanting a retrofit solution for an older home.
The New Zealand Building Code often asks for the bare minimum and by using this as a benchmark, the actual ventilation requirements of the property might not be met. Our code in New Zealand asks for 0.35 air changes per hour, however if you are really wanting to maximise your homes air quality this should be higher. When designing a Lossnay system, authorised Mitsubishi Electric installers refer to the higher UK standard of 0.43-0.5 air changes per hour.
Capabilities like this are important as they can easily be overlooked by price, but a low performing system can result in unmet expectations and ultimately a wasted investment.
While many systems including Lossnay can draw from moisture laden air, to get the most energy efficiency out of your heat recovery system, homeowners should install a separate Mitsubishi Electric Ducted Exhaust Ventilation Fan in wet areas such as bathrooms. While a bathroom can be warm during showers, when not in use they are often the coldest rooms in the home - so why combine that cold air to the air you are hoping to recover heat from and reduce the overall temperature you can recover? Exhaust fans do an excellent job at removing steam and moisture quickly and are turned off when not needed, saving energy use.

On the 9th of November 2021, Black Diamond Technologies Limited (formally known as MELCO) reached an important milestone – 40 years of providing New Zealanders with the leading edge technologies of Mitsubishi Electric products into New Zealand homes and businesses.
To celebrate, we share our story from the beginning and our thoughts on how we will continue to shape the industry over the next 40 years and beyond.
Right from the beginning Mitsubishi Electric manufactured world leading products founded on two key principles: quality and technological innovation. Video Recorders, Colour TVs and Audio Systems were examples of categories where Mitsubishi Electric led the way. Yet in the early 80's those products were not represented in New Zealand, in fact the brand was unknown here.
The foresight that led to the introduction of Mitsubishi Electric products in New Zealand by MELCO / BDT came from its founder Ron Woodrow.
Ron began his career at EMI in Wellington. With a keen interest in consumer electronics his attention was drawn to how video recorder technologies were advancing, particularly by Japanese manufacturers. The potential he could see convinced him to take a bold step. Leaving the security of EMI in 1981, Ron along with Pat Feehan set up a new venture called MELTRON to import Mitsubishi Electric products.
Starting off with video recorders, the product range quickly grew to include TVs, Microwaves and computer products.
Impressed with the success, after 1 year Mitsubishi Electric Japan became a 51% partner in the venture and MELTRON was renamed MELCO (Mitsubishi Electric Company). The business grew quickly, with its head office in Wellington; branches were also opened in Christchurch and Auckland.
In 1992, with the departure of Pat Feehan, the then Divisional Manager Ken Lilley purchased these shares and became Director.
From the first ever Mitsubishi Electric video recorder that was brought into the country in 1981, the HS-330 Model (pictured below), the brand grew from strength to strength.
In 1988, a new range was launched that featured a distinctive black slimline design and was packed with a host of advanced features. No other video recorder had more up-to-date features for the price. This range became known as the Black Diamond Series and was so popular, that from 1988 to 1998 it was New Zealand's best-selling video recorder brand. The advertising created around the Black Diamond name proved so powerful that it became a sub-brand in its own right, and was even used by other Mitsubishi Electric distributors internationally.
1984 saw the introduction of Mitsubishi Electric Televisions. Just like video recorders, it did not take long for New Zealanders to aspire to also have a Mitsubishi Electric TV take pride of place in their lounge. As a result, from 1993 to 1996, the large screen feature packed Diva Collection became New Zealand's best-selling TV range.
Another key defining Mitsubishi Electric product was the Cube Microwave. Introduced in 1985, its unique shape was a real conversation starter and became so popular; kitchens in the day had cabinetry purpose built to fit “the Cube”. As a true mark of Mitsubishi Electric quality, we still receive calls from customers with working Cube Microwaves that require rehoming, 36 years on!
From a marketing perspective, the philosophy has always been to be the aspirational brand and to have Mitsubishi Electric product seen as the number one choice in every category it contested.
This has involved creating messages that position Mitsubishi Electric products as stylish, advanced and very user friendly. For many years the memorable tag line for virtually all our products was “Don't you wish you had a Mitsubishi?”
In a business as dynamic as consumer electronics, change is inevitable. Organisations must develop resilience and flexibility to adapt. In 1997 Mitsubishi Electric underwent changes that saw it announce a global move away from TV and video recorder production. These had been important categories for MELCO / BDT however, like its Japanese partner; the New Zealand Company would also have to change. In 1998 the company re-established itself with Mitsubishi Electric, energy efficient, compressor driven products. It did not take long for the brand to firmly establishing itself in the air conditioning, dehumidifier and refrigeration markets, where it is now one of the major and leading players.
Part of this re-invention was also a change in company structure where Ron Woodrow and Ken Lilley bought out Mitsubishi Electric's 50% stake. With this change to 100% New Zealand ownership, MELCO changed its name to Black Diamond Technologies.
Through the exclusive partnership with Mitsubishi Electric, BDT has enjoyed the advantages of access to category leading technology and energy efficient, environmentally sustainable products with unique features to improve people's lives.
As a result, the company now specialises in the marketing and distribution of Mitsubishi Electric products including Air Conditioning and Heat Pumps, Ventilation, Hot Water Heat Pumps, Dehumidifiers, Refrigeration, as well as a full range of commercial building HVAC (Heating Ventilation Air Conditioning) solutions.
Integral to the successful change in direction was the joining of Darryl Rochester to the Company in 1999. Darryl came with a long history in the New Zealand air conditioning industry and was ready to take on the challenge of establishing Mitsubishi Electric as the leading brand of energy efficient compressor driven products.
While the first Mitsubishi Electric Heat Pump System was sold in New Zealand in 1989, real momentum started in 2006. Using the tried and tested marketing philosophy of leading with unique products that take the higher ground, New Zealand's quietest high wall heat pump was launched.
Just like all those years ago, the philosophy of being the aspirational brand and to have Mitsubishi Electric product seen as the number one choice was front and centre for the marketing of Mitsubishi Electric Heat Pumps.
The new “quietly superior” advertising campaign that featured the cat and presenter based format was born. And to this day, Mitsubishi Electric Heat Pumps are now unequivocally synonymous with quietness.
Since then, regular unique product ranges were introduced setting new standards in comfort levels. HyperCore Technology was launched in 2009 that was specifically designed for New Zealand's low temperature conditions. Colour options with the Designer Series was introduced in 2011 giving Kiwis an alternative to just white!
And in 2014 driven by the philosophy of smart technology, BDT took matters in their own hands and developed the Wi-Fi Control app in-house for its range of Mitsubishi Electric Heat Pumps sold in New Zealand. The successful advertising campaign was centred around the premise of “Never return to a cold home again” and absolutely changed the way New Zealanders thought about heat pumps.
Brought to life in 1998, the Environmental Vision 2021 initiative was established by Mitsubishi Electric with a long term global framework for realising a more sustainable planet. Since then, Mitsubishi Electric has reported annually on its environmental objectives and achievements in Japan and globally, to review the progress of the environmental plans of the group.
A key driver of the Environmental Vision 2021 Mandate is striving for the best and the most environmentally friendly use of energy in buildings by developing zero or low carbon technologies that consume the least amount of energy with minimal environmental impact.
The Mitsubishi Electric Ecodan Hot Water Heat Pump Range launched in 2020 is a good example of a product that already meets this objective. Utilising their expertise and industry leading technology, Mitsubishi Electric has developed a super energy efficient heat pump that combines both hot water heating and room heating through one system.
Just like heat pumps revolutionised space heating in homes in the early 2000's, hot water heat pumps are poised to take the same trajectory. They are set to become the building blocks of tomorrow's environmentally friendly future and BDT is committed to retain Mitsubishi Electric's leading position in the New Zealand market wherever the journey takes us.
On average, with buildings accounting for over 20%* of energy consumption and carbon emissions in New Zealand, improving the level of efficiency is of paramount importance.
As the exclusive distributor of Mitsubishi Electric products in New Zealand, BDT seeks to use its position to increase awareness, improve energy use and minimise carbon footprint in the built environment in the most energy-efficient, cost-effective and environmentally friendly way possible.
By constantly challenging everyone involved to combat the issues we all face, BDT and Mitsubishi Electric aim to help everyone address both energy use and carbon emissions, to work towards a more environmentally sustainable future overall.
BDT looks forward to regularly reporting back on how both BDT and Mitsubishi Electric are taking definitive action today, to create a greener world for tomorrow.

Mitsubishi Electric has extended the e-Series Modular Chiller Range to now include M1500-1800 models that utilise R32 as a low Global Warming Potential (GWP) refrigerant. Comprised of cooling only and heat pump models, the Mitsubishi Electric R32 range of e-Series Modular Chillers allow up to six individual units to be connected together to provide system capacities up to 1,080kW.
A modern update on traditional systems, the R32 e-Series Chiller is Mitsubishi Electric’s most efficient chiller system yet.

Available as a cooling only or heat pump version, the e-Series is suitable for both comfort and process cooling applications. The modular design is great for new or replacement projects and ideal for projects with future expansion plans – allowing for a reduced initial capital cost.
Mitsubishi Electric e-Series Modular Chillers are currently operating in New Zealand hotels and commercial buildings, as well as experiencing growth in industries such as horticulture, dairy and industrial processing plants due to its superior efficiency and versatility.
*(BS) Coastal Protection and (-N) built-in header type options available.
With the New Zealand Government’s ratification of the International Kigali Amendment in 2020 sparking a steep phasedown of HFCs, building owners, facility managers and the construction industry have been looking for HVAC systems that deliver high operational efficiency whilst minimising the GWP of the refrigerants used within these systems.
The new R32 e-Series Modular Chillers offer significant environmental benefits over conventional R410A chillers. The use of R32 compatible compressors and flat tube heat exchangers allows for approximately 68% reduction in refrigeration volume and approximately 89% reduction in CO2 equivalent in the EACV-M1500YC(-N)(-BS).
A new compressor with a suction chamber injection mechanism and an inverter control system that automatically controls the operating frequency realise the use of R32 refrigerant and a wide water operating range.
e-Series Modular Chillers offer significantly improved seasonal efficiency when compared to R410A e-Series machines, which means that they cost less to operate over their lifetime.
*The values are calculated in accordance with EN14511.
The use of high performance heat exchangers allows for a greater surface area whilst also keeping the units much narrower than conventional chillers. The inclusion of fins inside the flat tube heat exchanger divides the flow path of refrigerant and improves heat exchange effectiveness. This contributes to greater energy efficiency, reduction in refrigerant volume and a wider operating range.
Water Side Pressure Drop is reduced due to the new heat exchanger design. The heat exchanger assembly is complete with drain valve and air vents. These allow for easy air bleeding and draining of the heat exchanger.
Up to six individual units can be connected together to provide a system capacity from 150-900kW for the M1500 model or 180-1080kW for the M1800 model. Using this modular approach reduces plant space requirements as well as simplifying logistics and installation.
A modular approach also lends itself to a staged installation for future HVAC demands, as modular chillers can be scaled accordingly and are easily replaced.
When installed using the inbuilt headers, individual modules can be isolated from the water circuit thanks to the inbuilt isolation valves. This allows for maintenance to be carried out while the other modules remain in operation.
Typical chiller control systems allow units to run at a maximum capacity while other units are in standby during part load. The Mitsubishi Electric e-Series Chiller Range is designed to optimise chiller compressor frequency based on the number of connected units, maintaining the highest part load efficiency possible.
Typical Chiller Control
e-Series Modular Chiller Ranger with Optimum Frequency Control
With up to six units operating in one bank, this function improves system efficiency when operating at low to medium loads. Furthermore the run time of each unit is equalised by the control system, this prevents uneven wear on the units and extends the lifespan of the system.
The e-Series Modular Chillers are by their nature much quieter than conventional chillers. By utilising highly efficient fan and compressor technologies within a uniquely shaped chassis, the e-Series Modular Chiller range offers low noise levels that are ideal for high density areas such as city centres where commercial and residential buildings mix.
While the standard e-Series models come with excellent corrosion resistance, the Coastal Protection e-Series models (-BS) go a step further by treating external panels and other key elements to a higher paint specification, providing further protection from aggressive salt environments often needed in New Zealand.
The water temperature in each module can be controlled using local remote controller PAR-W31MAA or by using centralised controller AE-200E. The AE-200E controller can centrally control up to 24 units or 24 systems connected via M-Net. The maximum number of connectable units can be further increased using EW-50E or AE-50E Expansion Controllers.

The NZS5149 standard that deals with refrigerant concentration in confined spaces has been around since 2016. It’s important as it affects every new or altered DX system installed in NZ – but it is largely overlooked.
If you are designing or installing DX HVAC systems you need to know about NZS5149, as by not meeting the standard the consequence could be maximum penalties of $500,000 or up to 2 years’ imprisonment.
NZS5149 is a safety and environmental standard that primarily deals with refrigerant leakage and more precisely the risk of asphyxiation or fire that can result from any leak. The standard itself is around 200 pages long set out in four sections covering:
NZS5149 definitely is a tricky standard, but anyone working with a DX air con or DX industrial plant should be using it regularly.
Many of the old school refrigerants we have been using (like R410A) are class A1 refrigerants. These are non-flammable but somewhat toxic, so under NZS5149 they only have a toxicity limit. However many of the newer refrigerants (think R32, R1234ze, etc.) are A2 class, which means they are both mildly toxic and mildly flammable. These have the double whammy of both a toxicity and a flammability limit - with the stricter of the two being your overall limit. So any flammable refrigerant will likely be harder to make comply with the standard.
However as we're all aware many "old" gasses like R410A have high Global Warming Potential, so are in a heavy phase out period. Going forward you are more likely to have to deal with a "new" gas that has more stringent requirements.
Annexes B1, B2 and B3 in section one of NZS5149 will tell you all the details for the gas you have. These can be applied in to tables A1 and A2 in the same section - which is where you start to see what you are up for and how big the mountain is that you have to climb.
From a comfort cooling perspective hydronic systems generally have the chiller sited outside in the open air - so even though the volume of refrigerant in them could be large, 99% of the time they won't be a problem for safety under NZS5149.
Most 1:1 split systems usually won't be too much of an issue either, as often the refrigerant charge volumes they have are pretty small. So unless you have a high capacity split serving a small volume space these are unlikely to cause you any issues under NZS5149. The exception is floor console splits as these are mounted close to the ground which causes issues with the flammability calculation. Take care with these.
The real problem child is VRV / VRF systems as these often have a large gas charge with the refrigerant going right into occupied spaces - which can be small. Combine this with the heavy phase down of R410A gas that all large VRV / VRF systems use, and you can see why designers are moving away from these types of systems.
NZS5149 is also why you won't find any large VRV / VRF DX systems being offered in R32. There is simply no way they could comply with the more stringent flammability requirements of R32 - they have enough trouble complying with the lesser toxicity levels of R410A.
Now looking at applications, the standard sets out a sliding scale for requirements based on room occupancy. As you go up the scale the requirements to comply become more and more onerous.
In comfort cooling the potentially problematic DX systems are currently all either R410A or R32. So for a standard room the rough maximum concentration levels are:
R410A = approx. 1kg per 1m2 of any room served*
R32 = approx. 1kg per 6m2 of any room served*
*note assumes 2.4m floor to ceiling height. Ceiling void cannot be included in room volume.
In my experience mitigation for excessive refrigerant concentration will be expensive, difficult or both. So the first approach you should look at is changing the design to avoid exceeding the maximum concentration levels by:
If you can't do any of the above then you are up for mitigation, this can be found in section 3 of NZS5149. Some of the possible methods are:
A floor in a commercial building that has been separated in to 40x small offices with a VRV system proposed to condition them. Clearly an office is a class B application, so there is no limit on the system charge and no problem right? No, wrong!
In class B, any space that exceeds the maximum concentration limit still needs to have sensors and an alarm system. So if all 40 offices exceed the maximum limit we are up for approximate costs as follows:
Combined 10 Year Life Cost for Alarms = $302,000
As you can see the hidden cost can often be a lot more than changing to a different system type or another design related change.
Combined 10 Year Life Cost for Alarms = $302,000
BDT is a HVAC product supplier not a refrigeration supplier, so all comments are given from this perspective. Everything discussed is BDT's opinion or interpretation. Other opinions may differ. It is recommended you check any designs you do against the NZS5149 standard for yourself or engage a professional to verify your interpretation. Click here to read the full standard.

Selecting refrigerant driven HVAC plants based simply on capital cost, is easy. But have you ever considered the potential service delivery risks, or the financial and environmental repercussions of these decisions on the future?
It’s time to move away from our reliance on the “safe” relatively benign HFC refrigerants we have all become used to.
The New Zealand Government ratified the International Kigali Amendment in 2020, affecting all HFC’s and blends which of course are the work horse of the HVAC and commercial refrigeration industry.
The Kigali Amendment requires Montreal Protocol Parties to gradually phase down HFC production and use. In New Zealand a phasedown to 15% of an agreed base level will happen incrementally until the target is reached in 2036-2037. The refrigerant import volumes are capped based on CO2e (equivalent tonnes) and not on any one particular refrigerant.
This single piece of international legislation will be the main driver for refrigerant change.
Moving to HFO pure and compound blends appears to be the way the industry is going. HFO or Hydro Fluoro Olefins are fourth generation halogenated compounds that contain hydrogen fluorine and a double carbon bond.
They are typically low Global Warming Potential (GWP) and zero Ozone Depletion Potential (ODP). Most are A2L class and many are used in blends like R513A along with HFC’s and some naturals.
HFO’s when released into the upper atmosphere break down in days rather than thousands of years but there are potential issues around production of TFA (Triflouroacetic Acid) or more commonly known as acid rain. The long term environmental effects are not yet known, just like HFC’s when they were introduced.
R290 is of course highly refined propane and is already used in India, China and very soon the EU. With zero ODP, virtually zero GWP, and very low charge volume per kW, this will drive R290 as the solution for this massive market segment.
R290 is relatively cheap to produce, highly efficient and environmentally acceptable however the only fish hook is the risk mitigation around its A3 flammability. Our industry must find a way to deal with the safety issues of R290 sooner rather than later.
Changing from the staple “safe” A1 HFC’s to A2, A2L and even A3 solutions will create issues around safety risk mitigation.
AS/NZS 5149 requires safety systems that must be factored into ongoing cost projections, such as:
The first of many by Mitsubishi Electric is the development of the R32 hybrid secondary refrigerant VRF technology.
Back in 2014 when this technology was introduced the industry was very sceptical of the change but through persistence and brave engineering project decisions, Hybrid VRF is now 35% of our VRF projects and rising. There is over 11 megawatts of installed equipment in New Zealand, demonstrating this technology as a clear winner.
By using water as the heat transfer vehicle for the majority of the air conditioning system, Hybrid VRF reduces the overall amount of refrigerant in the system. Furthermore, with only water connecting the branch box to the indoor units, Hybrid VRF minimises the need for expensive leak detection leading to significant reductions in on-going maintenance costs in the controlled space that would be needed to comply with AS/NZS 5149 (1-4) 2016. Gains in sensible heat load capacities, higher air flows and more comfortable air off coil conditions have also been desirable off shoots of this technology.
AS/NZS 5149 is well overdue for review however there are no current plans to do so.
Government has indicated that refrigerant will be declared a registered product under the Waste Minimisation Act 2008. This will mean a mandated product stewardship scheme will be introduced encompassing a cradle to grave program, in the same way car tyres are handled - likely to drive mandatory refrigerant handling qualifications that don’t presently exist in New Zealand.
This will require registration and training for about, 7000 technicians over the next 3-4 years. Our system struggles to train 200 apprentices currently.
With higher risk refrigerants, fines for refrigerant accidental release and a shortage of trained technicians, ethical suppliers like BDT are going to have to step up to deliver a high level of technical service, field support and training to ensure security of supply.
Plant design and selection decisions need to be based on sustainable, efficient through life choices not “the cheapest current capital cost”, as those times are over.
The practical reality is that many current HVAC plants will have to be replaced before the end of its optimal life due to the unavailability and/or the cost of the refrigerant charge in the case of a catastrophic leak event.
The pending global warming catastrophe is driving this phasedown of the refrigerants we have used for the last 40 years.
We are a small country in the world scheme of things but with brave engineering decisions, we can future proof our country’s industries, our economy and our building stock to ensure we are leaders not followers in refrigerant roulette that will be the next 10 to 15 years and beyond.
Tuesday 26th of October 2021
Since the New Zealand Government ratified the International Kigali Amendment in 2020, the HVAC industry has had to rethink our use of traditional R410A VRF systems which we have all been comfortable designing and installing in past years.
With these legislative, comfort, safety and environmental pressures on the industry, coupled with the expectations of building owners seeking design and technology which will stand the test of time, Hybrid VRF using R32 refrigerant offers a future-proof solution to cater for the changing needs and expectations of our industry to succeed R410A VRF or VRV systems in the New Zealand market.
All the benefits of VRF with significantly lower GWP
The 2-Pipe Hybrid VRF System offers the same comfort levels normally associated with 4-pipe fan coil systems. In addition, consultants and end users will appreciate the same design flexibility, operational efficiency and advanced control that Mitsubishi Electric traditional VRF is renowned for.
The R32 Hybrid VRF Range brings all of the benefits of VRF air conditioning in an R32 format to deliver a system with a significantly lower Global Warming Potential (GWP) than existing solutions – the shift from R410A to R32 refrigerant realises a 66% reduction in Global Warming Potential.
Combat the rising costs of R410A refrigerant with R32
With the phase-down of HFC gasses particularly effecting R410A, the R32 Hybrid VRF Range provides the obvious answer for those customers looking for a future-proof heating and cooling solution that delivers advanced efficiency with improved corporate social responsibility and minimal environmental impact.
Water instead of refrigerant is at the heart of the indoor units – making it safer for occupants and less expensive to maintain
By using water as the heat medium for the majority of the air conditioning system, Hybrid VRF reduces the overall amount of refrigerant in the system.
Furthermore, with only water between the branch box to the indoor units, Hybrid VRF minimises the need for expensive leak detection leading to significant reductions in on-going maintenance costs in the controlled space that would be needed to comply with AS/NZS 5149 (1-4) 2016.
R32 refrigerant offers low environmental impact without compromising on efficiencies
There is now an expectation that the materials and chemicals used within a building have the least possible impact on the environment and the community.
An R32 Hybrid VRF System can require up to 52% less refrigerant for the same capacity when compared to an equivalent R410A traditional VRF system. R32 Hybrid VRF utilises a single composition refrigerant which has a GWP of only 675 and as a total system it can have an 84% reduction in the carbon dioxide equivalent.
The Synthetic Greenhouse Gas Levy and the Environmental impact with R32 refrigerant is significantly less, meaning that your building is in the best position for being ahead of the curve of change. And if there should be an unexpected leak in the system your costs and impact on the environment involved with re-charging the system will be significantly lower than if you were to install an R410A system. R32 Hybrid VRF is the lowest GWP VRF system in the New Zealand market today.
R32 refrigerant does not just offer a solution to our environmental pressures and phase down targets. From a thermodynamic perspective, R32 offers similar cooling efficiencies as well as improved heating efficiencies when compared to R410A.
Hybrid VRF futureproofs your investment ensuring your air-conditioning plant has the expected longevity, and gives you the assurance that the chemical refrigerant will not be priced out of the market by the means of the government imposed Emissions Trading Scheme on Synthetic Greenhouse Gasses and the International Kigali Amendment agreement.
Hybrid VRF, with its ever expanding product range and world leading technology, is a revolutionary product that is truly disrupting the HVAC industry.
Mitsubishi Electric has made significant strides in research and development of Hybrid VRF technology. In 2014, when Hybrid VRF was first introduced to the New Zealand Market by Black Diamond Technologies there were only 16 indoor units to choose from.
Fast forward to 2021 and there are now 53 indoor models on offer, including the introduction of larger capacity PKFY Wall Mounted Units, a new PEFY Ceiling Concealed High Static Pressure Range and new sizes within both the PLFY 4-Way Airflow and Compact Cassette Ranges.For more information contact your Regional Applied Products Sales Engineer or click here.

We spend up to 80% of our time inside. As such, good indoor air quality is paramount to our well-being. So how can home owners have the peace of mind they are breathing cleaner, healthier air all year round?
Introducing the Plasma Quad Connect – a new high wall accessory, featuring high-performance two stage plasma technology. The advanced filtration system works to clean away smells, dust, mould and other common household allergens, making it an ideal addition for asthma and allergy sufferers.
You may be surprised how contaminated indoor air can actually be. You might not be able to see it – but it is there! Every time you open your doors or windows, external pollutants such as pollen, dust and other allergens enter the home. But did you know oil and fat particles from cooking all release microscopic particles into the air too?
Dust and pet dander (dead skin flakes), mould build-up and mildew spores triggered by dampness can further increase concentrations of pollutants. There is substantial evidence to support the claim that breathing Particulate Matter (PM) is harmful to human health, particularly smaller fractions such as PM10 and PM5.
The Plasma Quad Connect is designed to work like an electrical curtain, using an advanced two-stage process which first makes plasma that breaks down air pollutants and then creates an electrical discharge that neutralises even microscopic particles in the air.
In fact, it can even capture particles as small as PM2.5, that's 20 times smaller than the width of a human hair! Unseen to the human eye, these microscopic particles can easily penetrate deep into our lungs and even our bloodstream.
The result? A more healthy and cleaner living environment that can be enjoyed year-round.
Independent test results confirm that the Plasma Quad Connect Filtration System achieves extremely high reduction results in the removal of allergen, mould, bacteria and virus particles in the room. This provides the ultimate peace of mind and ensures a healthier and cleaner living environment.
Designed to be installed directly above high wall units, the Plasma Quad Connect is compatible with the following High Wall Systems.
This slimline, advanced air filtration accessory provides a value-added sales opportunity when paired with compatible high-wall units.
Plasma Quad Filtration is built-in as a standard feature in the Black Diamond LN Series.

Not requiring installation in the attic, the new Vertical Lossnay Range resolves the issue of no roof space, offering an alternative installation solution. Now more homes can have a Lossnay Fresh Air Heat Recovery System, regardless of their design and installation challenges.
The Vertical Lossnay Range is designed specifically for the New Zealand housing market and makes energy efficient, super-quiet ventilation accessible to even more homes.
With a small and vertical upright design, the Lossnay Ventilation System is not limited to an in-roof installation and its compact footprint allows it to be placed in the garage or a cupboard in the kitchen. Now whole home ventilation can be installed and integrated in the overall building design without limitations.
Ventilating our indoor spaces is more important than ever, but we also need to be as energy efficient as possible. The new Vertical Lossnay will deliver fresh filtered air whilst recovering energy to minimise waste.
In fact, Lossnay’s unique heat recovery technology recovers up to 85% of the heat energy from the outgoing stale air which is then used to pre-warm (or pre-cool) incoming fresh air. This means any heating or cooling appliance does not have to work as hard to reach the desired room temperature – providing savings on your energy bill and maintaining a healthy home environment.
The quality of indoor air is an important factor for health and wellbeing and the new Vertical Lossnay Range ensures there is a constant flow of fresh air into our homes, and that potentially harmful pollutants and chemicals are being removed at the same time.
The new residential range comes with optional NOx (nitrogen oxide) and Particulate Matter Filtration, with a unique third filter pocket which can be used for additional filtration of NOx emissions.
This means that homes in even the most polluted environments can be supplied with clean, healthy air.
A built-in Automatic Summer Bypass also allows the units to bring in fresh air from outside without transferring heat, in order to reduce the risk of overheating.
This provides the ideal solution for cooling down a dwelling that may have overheated during the day once the outside temperature has dropped in the evening.
Using onboard temperature sensors, the unit can automatically enter Bypass Mode when it detects the space is hotter than desired and the outside air is cool enough.
A built-in LCD controller allows for easy control and commissioning of the unit, and offers a clear display showing normal, boost, and purge modes. Up to four speed settings can be commissioned digitally to ensure constant and accurate settings.

When selecting hot water systems for commercial and industrial applications, having a reliable system that will meet today’s needs now and those of the future is important. Mitsubishi Electric have developed QAHV; the latest innovation in a comprehensive line-up of Hot Water Heat Pump products. Specifically designed to produce high temperature potable hot water up to 90°C, the QAHV is suitable for commercial and industrial projects.
Using natural CO2 as the refrigerant, the QAHV provides one of the lowest environmental impacts when generating potable hot water. It is engineered to perform well in harsh conditions and climates, and of course being an inverter heat pump it does so extremely efficiently. By adopting Mitsubishi Electric's unique technology, the QAHV ensures highly reliable performance as well as high heating capacity even at low outdoor temperatures.
The industry is shifting. The Government has banned new coal boilers from the end of 2021 and businesses will need to phase out existing ones by 2037. Simultaneously the Government is providing $70M to support and incentivise businesses to switch away from boilers to cleaner, greener options for hot water production. While many may turn to natural gas, the Climate Change Commission is proposing no new gas connections to buildings from 2025 and a steep phase out of existing gas boilers from 2035 onwards.
Currently gas is used to produce hot water in the majority of commercial buildings in New Zealand, and while gas is an attractive option due to its compact footprint, it is a very high carbon emitter and isn’t particularly efficient, even if the building is using a modern condenser boiler – not to mention the potential risk to occupants if a leak occurs.
With the future of traditional forms of hot water heating uncertain, it is clear that those within the industry, engineers, designers, installers or owners, must move to new solutions for water heating in commercial buildings – and the move needs to start now.
The growing emphasis on global warming mitigation has stimulated interest in a new generation of low-GWP refrigerants, many of the new refrigerants being created feature GWP’s around 500 to 600 or even less. But nothing can compete with CO2 and its GWP of 1 – it provides the reference point for environmental impact that all other refrigerants are measured against.
The QAHV series utilises CO2 as it is an environmentally-friendly, safe and natural refrigerant with zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of 1.
There is no greener alternative currently available in New Zealand.
The Mitsubishi Electric QAHV System utilises a twisted and spiral gas cooler. This patented technology enhances energy efficiency while delivering high temperature hot water.
Using twisted pipes as water pipes and running the refrigerant pipes along their grooves helps to increase the heat-conductive area. The continuous spiral groove design accelerates the turbulence effect of water and helps to reduce pressure loss within the heat exchanger, enhancing efficiency.
Equipped with the latest inverter scroll compressor, QAHV offers unparalleled efficiency when compared to fixed speed systems - boasting an impressive COP of 3.88*.
*Under normal heating conditions at outdoor temp: 16°CDB / 12°CWB, inlet water temp 17°C, outlet water temp 65°C.
As ambient temperatures drop, so too does the capacity of heat pumps. However, the QAHV is able to provide its full heating capacity of 40kW even at ambient temperatures as low as -3°C. Furthermore, the unit operates to supply 90°C hot water in ambient temperatures as low as -25°C. This superior level of performance is achieved using Mitsubishi Electric’s industry-first Flash Injection Circuit which provides the optimum amount of refrigerant to the system via a compressor through a specially designed injection port. This ensures a highly stable operation that at the same time, meets the guidelines for Legionella.
As a single pass high temperature lift machine, QAHV works best with a high water temperature difference and delivers 10l/min or more of full temperature usable hot water in real time. This directly reduces the amount of storage required to meet the peak demands, and gives quicker recovery. Ideal for commercial uses where hot water demand is high, such as gyms, hotels, motels, aged care facilities and hospitals.
To help extend the life of the QAHV outdoor unit when located within highly corrosive environments, the optional Mitsubishi Electric “BS” Salt Corrosion Protection System can be applied during the outdoor units manufacturing process to ensure all components are 100% protected before the outdoor unit is assembled.
* Under normal heating conditions at outdoor temp:16°CDB/12°CWB, inlet water temp 17°C, outlet water temp 65°C
While its environmental-friendliness is QAHV’s leading strength and the key to future-proofing from climate change and subsequent government legislation and regulation, its superior performance is what really makes QAHV a smart investment.

Mitsubishi Electric has extended the Lossnay LGH Energy Recovery Ventilation Range to now include Sensible Heat Recovery Only models. The new range features a new non-permeable Lossnay Core that is specifically designed to recover sensible heat and remove moisture at the same time.
The newest addition to the Lossnay Range introduces fresh filtered air and thanks to the new core can now draw stale air out from areas with high humidity such as bathrooms, kitchens and laundries as well as commercial applications such as gyms, healthcare centres, schools and offices.
Furthermore, the range features easier installation, quiet operation, high energy efficiency and optimised control.
This system is designed to transfer sensible heat only (the heat you can feel as temperature changes) and maximises heat recovery from the stale outgoing air. In addition, due to the non-permeable core it also removes moisture in high humidity areas at the same time.
The available energy is transferred and re-used to pre-warm or pre-cool the incoming fresh air, maximising energy efficiencies. In doing so, moisture build-up is minimised while healthy humidity levels are maintained and managed for occupants throughout the entire building.
It is important to note that it does not recover latent heat, which is the additional heat contained in the airborne moisture in the air. The Sensible Lossnay System uses a non-permeable core so moisture cannot be absorbed by the core. For this reason, the system has a drain connection that is piped to waste.
Now you can bring fresh filtered air in and draw stale air out, even from high moisture areas - with the added benefit of Sensible Heat Recovery maximising energy efficiencies. The non-permeable Lossnay Core enables the system to ventilate all areas, including those with high humidity such as bathrooms, kitchens, gyms and health care centres.
Maintenance is made easier with the fully removable and washable core. The Sensible Lossnay design also includes a full drain pan which avoids mould and odour inside the unit by ensuring moisture is drained throughout all seasons.
The unit features one drain pipe terminal allowing for quicker and lower cost installation. Trap piping is not required as the new Sensible Lossnay unit features backflow prevention and an internal inclined drain pan, which not only helps with installation, but also reduces the risk of mould and odour.
Flexible ductwork and a swivel drain pipe mean installation can be incorporated into building designs with the ability to avoid obstructions and be set out of the way against walls.
Furthermore, the chassis of the Sensible Lossnay Range is lightweight, making installation easy and safe.
With models starting from 18dBA*, the Sensible Lossnay System includes a unique, specifically designed fan that optimises the balance between airflow and static pressure to minimise noise levels.
The new range also has an optional Silencer Duct that can reduce noise further when a quiet solution is paramount.
*on the lowest fan setting SPL @ 1.5m
Optimise airflow for each application with the new remote controller, PZ-62DR-E. Now featuring optional CO2 level indication, improved variable airflow control and a new fan speed timer.

Mitsubishi Electric has launched its latest addition to the already market-leading Ecodan Hot Water Heat Pump Range.
The ultra-quiet Ecodan Monobloc Outdoor Series has been expanded to include models that now utilise R32 refrigerant. As a more environmentally-friendly product with high operational efficiency, R32 has a low global warming potential (GWP) of 675 – less than one-third of the traditional R410A refrigerant.
Going forward, it will play a huge role in helping to reduce the environmental impact of compressor-driven appliances. What’s more, it’s also easier to reuse and recycle as it’s a single component refrigerant.
As a result, we’ll likely see R32 refrigerant swiftly become the standard for hot water heat pump systems going forward.
The monobloc range will be available from July 2021.
R32 model and capacity lineup
With higher density housing becoming more common in New Zealand, the quiet outdoor operation is essential if you want to keep your neighbours happy. Designed specifically for residential applications, the new Ecodan outdoor units are extremely quiet - as low as 45dBA!*
Specific design features enable the quiet outdoor operation to be maintained at all times. This ultra-quiet operation means homeowners can now choose the most convenient location for their Ecodan without disturbing their neighbours.
Mitsubishi Electric has always been at the forefront of improving technology, including sound levels, to meet the ever-changing requirements of consumers. So it should come as no surprise that with the urban landscape rapidly changing to more high-density housing, Mitsubishi Electric has specifically tackled outdoor sound levels across the R32 Ecodan Range.
As part of the Ecodan outdoor range expansion, a new D-Generation of hydrobox and packaged cylinders has been released to specifically match the R32 outdoor units.
Ecodan provides continuous hot water via a dedicated “all-in-one” Ecodan Hot Water Storage System. These D-Generation storage systems are specifically designed to integrate with the R32 Ecodan outdoor range.
In addition to a 200L capacity, a smaller 170L*3 and a larger 300L packaged cylinder have been added as part of the D-Generation lineup.
The cylinders are completely pre-plumbed and wired for ease of installation.
A highly adaptable solution for retrofit and new builds. For systems where a 3rd party cylinder with a heat exchanger coil is required, this can be easily catered for by the addition of a 3-way diverter valve to the system and connecting it to the FTC5 Controller.
While identical in look and footprint compared to the previous generation, the D-Generation now features:
Installation improvements have been made to the pipe position and longer adjuster bolts are at the base of the cylinder.
Did you know traditional electric hot water heaters produce up to three times the amount of greenhouse gas compared to a low emission alternative such as a hot water heat pump?
Instant gas hot water systems contribute to even greater greenhouse gas emissions. By producing a staggering seven times more emissions compared to hot water heat pump technology.*1, this makes water heating one of the largest single sources of greenhouse gas emissions from the average Kiwi home. This is evident to such an extent that EECA (Energy Efficiency & Conservation Authority) has identified heat pumps as playing a key role in significantly reducing costs and greenhouse emissions from energy use.
An estimated 67% of New Zealand homes use a traditional electric hot water system*2. Substituting existing, less efficient technologies with their more efficient counterparts, such as a hot water heat pump, can contribute to a significant reduction in overall greenhouse emissions.
If you are looking for a super energy-efficient water heating solution that is also kind to the environment, Mitsubishi Electric Ecodan Hot Water Heat Pumps are the natural solution.

Heat pumps are adopting a new energy rating scale and label, based on the international Seasonal Energy Efficiency Ratio (SEER) methodology which identifies how air conditioners perform in different climate zones. The new rating scale will assess winter heating performance more accurately for New Zealand consumers.
Air conditioners and heat pumps sold in New Zealand must, by law, comply with Minimum Energy Performance Standards (MEPS) and Mandatory Energy Performance Labelling (MEPL)/Energy Rating Label (ERL) requirements.
As such, new air conditioner regulations will be reflected in a new label called the Zone Energy Rating Label (ZERL). These regulations have already been adopted in Australia and are expected to become mandatory in May 2021 for New Zealand, dependant on Cabinet sign-off.
Six months’ notice will be provided via the official Government newspaper and authoritative journal of constitutional record ‘The Gazette’ before the new regulations come into force in New Zealand.
Mitsubishi Electric is in a period of transition where you will start seeing new products or revisions registered under the new SEER regulations and displaying the new ZERL. This gives consumers and installers more information about which air conditioner will perform best in their climate zone.
Our Black Diamond Series High Walls, the new EcoCore Designer Series High Walls and RapidHeat Floor Consoles with R32 refrigerant are the first products to adopt these new standards.
For more information about the new labels contact your nearest Territory Representative.

The Mitsubishi Electric Climaveneta INTEGRA Range has been extended with the addition of the new i-FX-Q2-G05 multipurpose outdoor unit.
Utilising the more environmentally-friendly R513A refrigerant, the system simultaneously produces heating and chilled water using two completely independent hydronic circuits.
These heat pump chillers now exceed the minimum seasonal efficiency tier imposed by the ErP (Energy-related Products) Directive 2009/125/EC, effective in Europe from January 1st 2021.
The range offers high annual efficiencies achieved through inverter technology and uses low GWP R513A refrigerant.
With a GWP of only 631, R513A refrigerant has a significantly smaller carbon footprint compared to traditional systems utilising R134A.
Furthermore, the refrigerant is also non-toxic and non-flammable (Class A1 according to ISO 817).
This makes it the best choice for projects that require an eco-sustainable energy efficient solution.
The move to R513A is in line with a worldwide phasedown of the production and consumption of hydrofluorocarbons (HFC), moving away from traditional HFC refrigerants such as R134A to more environmentally-friendly, energy efficient blended refrigerants.
Thanks to the use of full inverter screw compressor and EC fans, the unit guarantees optimal energy efficiency for the system.
This high efficiency translates into reduced energy consumption throughout the year for any mode of operation, no matter what the outdoor conditions are.
In a traditional comfort application, an HVAC plant works at maximum power only for a limited number of hours per year. Therefore, it operates at part load conditions most of the time.
The new i-FX-Q2-G05 multipurpose units use the latest variable-speed technology in all the main components. With their accurate design, these models achieve greater efficiencies compared to similar fixed-speed units, with any combination of heating/cooling load in any season.
As these models incorporate variable-speed screw compressors, the system is able to effectively achieve any combination of load required by the HVAC plant.
Furthermore, it features superior Total Efficiency Ratio (TER) efficiencies of up to 19% higher when compared to units with fixed-speed compressors.
These higher efficiencies have been obtained by calculating both SCOP and SEER efficiency parameters with the variable water flow calculation method. As such, this takes full advantage of the variable speed technology of the i-FX-Q2-G05.
To allow the unit to manage the variable water flow, the standard configuration of the hydronic modules and flow controls has slightly changed. Now, the unit is able to control the activation and the speed (via a 0-10V signal) of an external variable speed pump both on the evaporator and on the condenser side.
The inverter's ability to continuously change the compressor speed provides reduced sound emissions, especially at part load to maximise acoustic comfort.
The i-FX-Q2-G05 Range is available in three noise options:
Inverter technology provides the added advantage of no in-rush current.
Sudden power surges and variations in the starting torque are minimised. Additionally, possible disturbances to the power grid are eliminated. As a result, lowering stress on electrical components and improving the reliability of the system.
The frequency converters selected are characterised by a Displacement Power Factor between 0.97 and 0.99. As a result, the Unit Power Factor under nominal operating conditions is always higher than that of a similar unit without inverter technology.
The i-FX-Q2-G05 utilises W3000TE Software, which is characterised by advanced functions and algorithms for optimum control. As such, it ensures a rapid adaptive response to the different dynamics of the plant, in all operating conditions.
Access to the controller is through the innovative KIPlink Interface. With more versatility than the traditional keyboard concept, users can operate the unit directly from their smartphone, tablet, or laptop.

With this in mind, now is the ideal time to expand your business into the hot water heat pump market.
After the country has seen record sales for June in many sectors
across New Zealand, there is a real feel of confidence in the domestic
This is evident in the levels of building consents granted. The latest data from Statistics New Zealand shows that despite seeing a dip in building consents during lockdown, they have bounced back with a rise of 64% this June*. Will it last? We think so. The pessimistic outlook would see a reduction in building consents moving into next year. However, this is likely to rebound for a number of reasons. One of the key drivers of this is the influx of Kiwis looking to return home during these uncertain times.
*Data sourced from Statistics New Zealand.
There is something to be
said about having time to think. Many Kiwis over the lockdown have
re-assessed how they spend and it’s really showing in the number
refurbishments and new build consents in the last month.
Recently, we aired our new Ecodan TV ads which have stirred up many end-user enquiries and shows the potential for this market. New home builds are still going ahead as well as plenty of renovations and replacement jobs for those Kiwis who are no longer going abroad for holidays. Instead, they are using the time and money to get projects done around the house.
One of the biggest things homeowners are researching is how to reduce their hot water and heating bills to future-proof their house and livelihoods. We see this year as an opportune time for your business to invest in Mitsubishi Electric Ecodan Hot Water Heat Pump Technology as Kiwis turn to alternative means to heat their home and save on running costs.
For the hot water heat pump market, the future is bright. At Black Diamond Technologies, we are here to support you and your company with this emerging technology.

Mitsubishi Electric Lossnay Single Room Ventilation is designed to provide cost-effective energy recovery ventilation to one specific area in the home. In addition to the wall-mounteed VL100 Single Room Ventilation System, we have extended the range to now also include a ducted model that is the perfect unobtrusive in-ceiling solution.
Stale air with higher levels of CO2 is a common problem not only in schools and offices but also in homes where structures are becoming more and more airtight due to more stringent building regulations.
High levels of CO2 can affect concentration and learning as well as overall wellbeing and productivity. Furthermore, the lack of natural ventilation in airtight spaces can lead to the build-up of moisture-laden stale air. This is the perfect breeding ground for mould that can trigger allergy or respiratory problems.
The option of leaving doors and windows open to allow fresh air to enter is not always desirable or practical, with potential security risks and greater exposure to outdoor noise.
This is where a fresh air ventilation system like Lossnay can make a real difference.
The Lossnay VL100 Range includes a ducted model that is the perfect unobtrusive in-ceiling solution. For applications without adequate roof space, there is a ductless unit purpose-built to accommodate a simple back-to-back wall hung installation.
The balanced pressure ventilation system captures and filters fresh outdoor air (as opposed to stale attic air) to replace indoor stale air for an all-round healthier, drier and warmer room.
The Lossnay Core recovers energy from the extracted stale air, to pre-warm or pre-cool the incoming air.
As a result, an existing heating appliance in the room does not have to work as hard to reach desired temperatures, maximising energy efficiency and reducing your energy bill.
This ducted model is specifically designed to provide energy efficient ventilation to ensure an individual room has a constant supply of filtered fresh air whilst minimising moisture build-up. Furthermore, incoming air is pre-warmed (or pre-cooled) so your existing heating appliance does not need to work as hard to reach desired temperatures.
Key specifications of the VL100 Ducted
This wall mounted unit provides an effective balanced pressure ventilation solution for a specific area up to 90m2*. Lossnay recovers energy from the air being transferred to pre-warm (or pre-cool) the fresh air drawn into the room. As a result, moisture build-up is minimised and a warmer, drier and healthier indoor environment can be maintained all year round.
Because this model is ductless in design, it is ideal for applications where there is no roof space to accommodate the heat exchanger and duct work.
Key specifications of the VL100 Wall Mount
In winter a traditional ventilator captures fresh air at the cold outside temperature. Lossnay Ventilation preheats the outside air before bringing the fresh, filtered air inside.
In summer a traditional ventilator captures fresh air at the hot outside temperature. Lossnay Ventilation lowers the outside air temperature before bringing the fresh, filtered air inside.

In the hot water heat pump market we focus a lot on efficiency and payback period. This is certainly important but what else makes these solutions practical and beneficial to the installer and the homeowner?
To aid the modern applications of buildings and environmental impact, Ecodan Hot Water Heat Pumps have many features that add a high amount of functionality and assistance to the installer and end-user.
Many underfloor heating (UFH) installations involve wet cement poured over the UFH pipework and then has to set. The tricky part is the dry time where it’s pivotal to prevent any cracking or unwanted movement, especially when another floor layer is added on top of the dried concrete.
Ecodan solves this by using Floor Dry Up Mode which lets you set step increment by as little as 1°C for 1 to 7 days to reach the desired UFH temperature. This method can be used to dry the concrete out and remain at target temperature whilst new flooring is added.
The Dry Up Mode can be programmed to suit the concrete type and installer preference for the build, making this one of the most practical features for UFH applications on the market.
Ecodan controllers have several ways to analyse the system again to help the installer and homeowner / tenant.
The SD Card System Analysis will start recording the system including:
Ecodan can be controlled by connecting a MelcoBEMS Mini Interface to the indoor control board. MelcoBEMS Mini is a MODBUS interface that can enable the hot water and heating solution to be controlled and monitored by a high-end home automation or building management system in a commercial environment.
This setting on the remote controller displays the energy consumed and delivered so the end-user can understand when the most energy is used and can check the consumption is low; especially if there is a high-cost electricity bill that month. We can take it one step further by adding smart energy meters to accurately monitor the electricity consumed using the Smart Grid Ready function. In addition to this, the user can set up auto recovery after power failure so the Ecodan System turns back on with all its settings as it was left and will continue to monitor energy use.
Ecodan Hot Water Heat Pump Systems are the most capable systems on the market, delivering functional and practical capability for both the installer and user. In this day and age with demands for quick, cost-effective application coupled with ongoing benefits, the Ecodan System is leagues ahead.

As BDT and Mitsubishi Electric grow into the new era of sustainability and environmental awareness, one thing has become very clear; systems comprising of water will play a large part in the transference of heat in the commercial HVAC market globally in the coming years.
Hybrid VRF (HVRF) bridges the gap between VRF / VRV solutions and heat recovery chiller plant, offering an alternative to common hydronic systems while still retaining the inherent benefits associated to the water-based options.
The HVAC market has been using water as a refrigeration and heating medium for many years, with chilled water being a safe, reliable refrigerant with a number of beneficial characteristics. Chillers, hot water heat pumps and 4 or even 6 pipe hydronic solutions have been utilised in large commercial buildings for many decades.
Heat recovery chiller systems are considered the crème-de-la-crème of HVAC solutions, incorporating the inherent efficiencies only possible through heat recovery with the comfort and security of water as the medium being circulated into occupied spaces. However, these have been a largely uneconomical option for small to medium scale applications.
The Hybrid VRF (HVRF) product category bridges the gap between VRF / VRV solutions and heat recovery chiller plant, offering an alternative to common hydronic systems while still retaining the inherent benefits associated to the water-based options.
Hybrid VRF places itself in the market as an economic hydronic heat recovery solution which can be applied from high-end residential homes and the small commercial market right through to a large scale modular solution.
With the adoption of global initiatives to reduce greenhouse gases and local legislative requirements with regards to occupant safety, HVRF provides design engineers and mechanical contractors the mitigation of risk associated with circulating refrigerants into occupied spaces. Furthermore it also reduces the potential global warming impact the larger refrigerant volume imparts; offering a saving on associated costs.
In the New Zealand market alone, BDT have seen a huge uptake of Hybrid VRF in the market. With over 5MW of heating capacity ordered to date across 42 projects Hybrid VRF applications are growing.
The largest Hybrid VRF project in the New Zealand market currently in construction incorporates 512kW cooling and 575kW of heating across 11 HVRF systems and is due for completion in FY21. This scale of project is a prime example of situations where a hydronic solution could have been applied however the HVRF alterative offered ease of construction, cost savings, modularity and redundancy reduction in the case of a mechanical failure.
Of course on the other hand, smaller systems can offer the benefits of hydronic architecture to projects that may be of a scale in which it is not economic to outlay the capital cost associated to a 4 pipe solution.
One such case is PGG Wrightsons Seeds wherein the developer Ngai Tahu was seeking to design a water-based system for their new building in Lincoln. The prerequisite was for a hydronic, water-based design for occupant comfort and safety reasons. In this instance, Hybrid VRF was the nominated solution to meet the hydronic requirements while offering the installation advantages of a modular VRF system.
In commercial buildings, additional leak detection systems specific to air conditioning are often installed to safeguard occupants due to increasing safety regulations. This affects hotels in particular, where air conditioners are installed in the room space and occupant safety is critical.
A leak detection system is designed to trigger an alarm if refrigerant was to leak into the room space and initiate an evacuation of the area to try and prevent harm to the occupants. These systems can be expensive and add to the cost of design, build and maintenance.
The small footprint and modular design means building owners can now take advantage of a manageable phased installation.
GWP is a measure of the global warming potential as compared to CO2 which has a unitary GWP of 1. R32 refrigerant is zero ozone depleting (ODP)and has a GWP 66% less than R410A. For example R410A will hold 2,088 times more heat when released in the upper atmosphere than the equivalent amount of CO2 would.
R32 refrigerant is being adopted by Mitsubishi Electric as an important step in the process towards the ultimate goal of a zero ODP, zero GWP, efficient, safe, and non-toxic refrigerant.

Climaveneta INTEGRA sets a new standard in the more environmentally friendly, simultaneous generation of heating and chilled water by combining the functions of a traditional boiler and chiller within a single unit.
Starting at around 44kW and with the option of integrating with a +2P Module, INTEGRA also allows for the production of high-temperature hot water up to 78°C.
Delivering high energy efficiencies, maximum integration and total reliability for year-round comfort, INTEGRA is perfect for hotels, hospitals, offices and shopping centres which have a high demand for heating and chilled water.
With the ability to produce cooling and heating capacity simultaneously from a single unit, you no longer need to install multiple machines to deliver effective hot and cold water.
In modern buildings characterised by opposite overlapping loads, INTEGRA represents the most advanced solution. INTEGRA guarantees comfort throughout the year independently and with maximum efficiency. Its construction philosophy has been designed to maximise the full effect of the unit in all working conditions, and especially in the case of simultaneous heating and cooling.
INTEGRA utilises advanced heat recovery technology to lessen energy consumption and operating costs. This is achieved by taking the heat energy from an area which needs to be cooled and heats areas that need to be warmed, so the system doesn’t need to work as hard to reach the desired temperature.
With the use of efficient technology such as heat recovery, this solution supports progressively more challenging regulatory restrictions about the environmental impact of the building. INTEGRA respects the environment and may help increase the value of the property.
By producing hot and cold water with the single unit, INTEGRA compares favourably with the more traditional combination of separate chiller and boiler. This also lowers initial investment and maintenance costs.
The plant room spaces and site operations are reduced, with substantial savings in terms of time and cost. INTEGRA satisfies the most daring architectural solutions and ensures optimum use of the building.
All air conditioning systems, as well as INTEGRA units, are normally selected to cover the peak load. This means that for most of the year units are operating at partial loads. For multi-purpose systems, this condition can occur more than 8,000 hours annually.
This is the reason why INTEGRA ensures maximum efficiency at partial load; a design focus that stems from the awareness of the real operating conditions of the unit and is accentuated in models with inverter technology – the exclusive i-FX-Q2 unit.
INTEGRA Systems are derived from Climaveneta’s long experience proven by over a thousand prestigious projects from all over the world.
Located at many different latitudes, all the installations share high energy efficiency, maximum integration and total reliability. All this as a result of the unique Climaveneta experience.

With the pressure on R410A refrigerant increasing, Mitsubishi Electric’s commitment to reducing the environmental impact of air conditioning has seen the introduction of New Zealand’s first VRF (Variable Refrigerant Flow) solution that has adopted R32 refrigerant.
Mitsubishi Electric has long been a leader in the world of air conditioning and the world’s first R32 Hybrid VRF Product Range again puts the company at the forefront of the industry.
Hybrid VRF utilises low GWP refrigerant R32, providing a real solution that delivers high operational efficiency whilst minimising the Global Warming Potential of the refrigerants used within these systems.
Having already introduced R32 refrigerant across its residential M-Series and commercial P-Series Split System Ranges, it was only a matter of time that Mitsubishi Electric tackled the VRF / VRV market with a solution that also adopted a low GWP refrigerant like R32.
The Mitsubishi Electric R32 VRF Solution is an evolution of Mitsubishi Electric’s Hybrid VRF System. First introduced in 2014, this unique 2-Pipe Hybrid VRF System combines VRF and chiller technologies using water throughout the majority of the pipework to efficiently transfer simultaneous heating and cooling to different rooms.
By using water as the heat transfer medium for the majority of the air conditioning system, Hybrid VRF reduces the overall amount of refrigerant in the system. Furthermore, with only water connecting the branch box to the indoor units, Hybrid VRF minimises the need for expensive leak detection leading to significant reductions in on-going maintenance costs in the controlled space that would be needed to comply with AS/NZS 5149 (1-4) 2016.
The 2-Pipe Hybrid VRF System offers the same comfort levels normally associated with 4-pipe fan coil systems. In addition, consultants and end-users will appreciate the same design flexibility, operational efficiency and advanced control that Mitsubishi Electric traditional VRF is renowned for.
In short, the addition of R32 to the Hybrid VRF Range brings all of the benefits of VRF air conditioning in R32 format to deliver a system with a significantly lower Global Warming Potential (GWP) than existing solutions. In fact, the shift from R410A to R32 refrigerant realises a massive 66% reduction in Global Warming Potential.
Over the last 5 years, Hybrid VRF applications have already enjoyed significant growth in New Zealand. These systems have been successfully incorporated in a variety of designs ranging from offices, hotels, retirement villages, education facilities, medical centres and much more.
With the phase-down of HFC gasses, particularly effecting R410A from next year, the introduction of the new R32 Hybrid VRF Range now provides the obvious answer for those customers looking for a future-proof heating and cooling solution that delivers advanced efficiency with improved corporate social responsibility and minimal environmental impact.
R32 Hybrid VRF is the new era of VRF in the market. Mitsubishi Electric has strived to design a system which not only meets the legislative requirements being imposed on the market today but also meets the future requirements that our market will have to adhere to.
The demand for high energy efficiencies, low Global Warming Potential and improved corporate social responsibility is increasing. As a result, regardless whether operating on a global, national or regional basis, all businesses are being forced to look at their own buildings and how their decisions on capital plant will impact them over the lifespan of the product. As such, R410A systems are becoming less viable with the cost of refrigerant increasing, with R410A cost per kilogram climbing rapidly based on the high GWP and the ETS Tax imposed.
As business owners, design engineers, installers and suppliers of HVAC systems in New Zealand, it is our duty to provide the developers and building owners a robust future-proof solution to best suit their building and occupants needs. It is also imperative we observe occupant safety and ensure our decisions will not have a lasting impact on our environment for the future.
BDT and Mitsubishi Electric are dedicated to leading the market with innovative products and initiatives which ensure our social corporate responsibilities are upheld; protecting ourselves, our stakeholders and the public.

Everyone knows how distracting a loud humming indoor unit can be. So in our industry, we commonly refer to how noisy a heat pump is based on the indoor unit sound levels. However, what is often overlooked is the sound level of the outdoor unit. Housing the compressor, it has the potential to create a significant level of unwanted noise.
Mitsubishi Electric has always been at the forefront of improving technology including sound levels, to meet the ever-changing need of consumers. So it should come as no surprise that with the rapidly changing urban landscape to more high-density housing, Mitsubishi Electric has now specifically tackled outdoor sound levels.
Ecodan has always been one of the quietest hot water heat pumps on the market. And with the introduction of the new ultra-quiet Ecodan Range, it has taken hot water heat pumps to the next level. These new models offer superb style, market-leading energy efficiency and sound levels. Designed especially for residential applications, the 6.0kW, 8.5kW and 11.2kW units are 3dBA quieter than previous models.
With higher density housing becoming more common in New Zealand, quiet outdoor operation is important especially if you want to keep your neighbours happy.
The new Ecodan Range features an industry-leading sound pressure level of 45dBA*, measured at a distance of 1m.
As a result, the system offers greater placement flexibility as the outdoor unit can now be located much closer to property boundaries. This makes the Ecodan Hot Water System ideal for areas sensitive to outdoor noise without disturbing the neighbours.
Our market-leading Ecodan Hot Water Heat Pump solutions are designed to provide a home with ultra-quiet, hot water heating and space heating with year-round energy efficiency and reliability.

Potable hot water heating in the commercial and residential sectors can be a large part of a buildings electricity demand. So, it makes sense that only the best solutions to heat this water as efficiently as possible are considered in any new builds or retrofits.
At Mitsubishi Electric, this need has been a driver for the inclusion of PWFY-BU modules in our Range of City Multi R2 Heat Recovery Systems which recovers heat rejected from your office space, and transfers this into your potable hot water cylinder. This technology incorporates a 12.5kW water module that connects to your R2 System via the Branch Controller, and is capable of providing 70°C hot water via the cascade-based R134a secondary refrigerant system in the water module.
This technology has been used in residential properties, medical facilities, veterinary services and hotels / motels across the country.
However, as the building stock in New Zealand can be quite diverse and water usage patterns vary immensely, there is a need to offer a broad range of potable hot water options to suit the needs of the market.
At Black Diamond Technologies (BDT), we understand this and as such, offer a wide range of options to suit the commercial and residential markets. See the list below of all the various ranges BDT can offer to suit your application.

When Ruapehu Ski Club was looking to replace hot water facilities in one of their buildings called ‘The Lodge’ on Mount Ruapehu, the club wanted to find a modern, efficient way to provide these important creature comforts for their club members
A major part of RSC’s aim when doing this refurbishment was to reduce the peak load of electricity used during the ski season. They required a hot water heating system that would work in the cold climate and still produce hot water efficiently.
The club building is able to house up to 70 people as well as leisure, cooking, wash facilities and ski workshop facilities.
Five existing hot water cylinders which used direct electric elements providing 900 litres of potable hot water needed to be replaced, alongside the heater in the drying room which consisted of a fan blowing over a 6kW heating element.
The Hot Water Solution
The installation consisted of two 11.2kW Ecodan Hot Water Heat Pump Hydrobox Systems and two 600L Hot Water Storage Cylinders. The outdoor units incorporate the Mitsubishi Electric patented Zubadan Flash Injection Technology which means they are able to maintain their full 11.2kW capacity with 55°C hot water output down to an ambient temperature of -15°C; suitable for the alpine conditions at Mt Ruapehu.
The Ecodan Hydrobox contains hydraulic components, pump, expansion vessel, flow sensor and a refrigerant to water heat exchanger, making it simple to connect just water piping to the cylinders. The two 600L Cylinders contain 40m coils to maximise the heat exchange inside the cylinder. Three temperature sensors are mounted in each cylinder to monitor the tank temperature from top to bottom.
Modulating control valves have been installed to balance the hot water provided by each of the two independent systems, allowing for automatic isolation of each cylinder if temperature cannot be maintained. Electric immersion elements are also installed in the hot water cylinders. These are controlled by the Building Management System to provide additional heating capacity if required during periods of high hot water consumption and to provide legionella prevention at scheduled intervals. The elements also serve as a backup heat source if the Ecodan Systems are shut down for maintenance. The club can reduce peak electricity consumption using the integrated FTC5 Controllers scheduling function so that hot water recovery times are outside of kitchen operating hours.
As the drying room is in continuous use during the ski season, an inverter driven 3.5kW HyperCore High Wall Heat Pump provides ample heat and is also controlled remotely depending on occupancy, further improving efficiency in place of the 6kW fan blown heater.
The BMS Solution
BDT provided a Building Management System to monitor and control the domestic hot water and space heating systems in the lodge. The controls package consisted of a web-enabled Black Diamond Controls Central Controller, BACnet Controller and three MelcoBEMS Mini’s to provide Modbus interfaces to the Mitsubishi Electric Ecodan and HyperCore Systems.
In addition, the site energy consumption is monitored via a newly installed Modbus Energy Meter connected to the main incoming supply. This allows the club to monitor their year-on-year energy savings and real time consumption.
Due to the remote nature of the site, the control system was developed to provide redundancy and automated email paging in the event of faults or persistent low hot water temperature situations.
The BMS provides a web interface which allows specific club member access to remotely monitor and adjust operating parameters such as temperature set point and time schedules, via a secure connection.
This system has seen its first season on the mountain, having successfully delivered hot water to Ruapehu Ski Club and we will continue to monitor the system year on year.

State of the art energy monitoring and management of the Ecodan Heat Pump System means families now have the visibility and freedom to efficiently manage their overall household power consumption for heating and hot water. Energy monitoring and control ensures households can take advantage of off-peak tariffs or improve the use of solar panels, providing them the ability to save even more on their power bill.
End-users can now easily check the energy data of the Ecodan Heat Pump with the ability to view electricity consumption and heat output on the remote controller.
Data Shown on the Remote Controller
Our advanced Auto Adaptation Function measures the room temperature and outdoor temperature, calculating the required heating capacity for the room.
The flow temperature is automatically controlled according to the required heating capacity, while the optimal room temperature is maintained at all times; ensuring the appropriate heating capacity and preventing energy wastage.
Future Room Temperature Estimation
By estimating future changes in room temperature, the system works to prevent unnecessary increases and decreases in the flow temperature. Auto Adaptation maximises both comfort and energy savings.2-ZONE CONTROL
Using Ecodan, it is possible to control two different flow temperatures, thereby managing two different heating load requirements. The system can adjust and maintain two flow temperatures when different temperatures are required for different rooms; for example, controlling a flow temperature of 45°C for the bedroom radiators and another flow temperature of 35°C for the living room underfloor heating.

The exact origin of using water for heating has some debate, but it dates back to around the 13th century where monks diverted river water and heated it in furnaces to warm their monasteries. With warm buildings in the cold months, the benefits of this ingenuity were obvious and over the years inventors and engineers have gradually found ways to improve on the concept. Following the industrial revolution, Charles Hood wrote the first engineering handbook for hot water heating in 1837, which was published in revised editions for 50 years.
Hydronic heating systems are commonly used throughout Europe and other parts of the world. In fact today, over two thirds of the world use warm water central heating.
So why is water such a good option to use?
If you remember back to school science class, water has a very high “specific heat capacity”. What this means for us is once the water is up to the desired temperature in our heating circuit, the water holds its heat energy well. Therefore it is a good substance to use to distribute heat.
The benefits of using heating circuits are:
What About Efficiency?
The ideal temperature to run underfloor heating is ideally somewhere between 35°C and 40°C (radiator temperatures vary according to the output capacity of the radiator). This makes using hot water heat pumps ideal for supplying heat to the emitter.
When using gas or oil boilers the temperature of the water coming out of these systems is too hot for underfloor heating. As a result the water needs to be blended down in temperature to mitigate the risk of overheating the house or even damaging the floor. Aside from this, the carbon emissions of these types of heating by comparison to a heat pump is significantly higher. Gas has over 5 times the emissions and oil boilers have over 8 times the emissions of heat pumps.* This is thanks in part to the clean electricity provided to us in New Zealand by the hydroelectric stations and in part to the high efficiency of the Ecodan Air to Water Heat Pumps.
When choosing central heating, Ecodan is unrivalled for performance, efficiency and carbon emissions.*Based on New Zealand electricity grid emission factors for 2015 (MBIE) and using average COP values for Ecodan Air to Water Heat Pump based on BSEN14511 testing.
In the commercial arena using water is commonplace because these efficiencies have a direct implication on budgets, as building owners take in to account running costs as a part of their budget forecast. If running costs, efficiency and being eco-friendly is so important to those building large buildings, how much more important should it be to homeowners running their own homes?
When clients who design or install commercial heating systems hear about these systems they can immediately see the benefit and understand the concept as this applied engineering used in the commercial world directly translates into what we are doing domestically.Why Ecodan?
The Ecodan Range by Mitsubishi Electric is unrivalled for performance, efficiency and quietness. Crucially with hot water heat pumps you want the heat pump to deliver all the heat you need without backup or supplementary heat sources.
With New Zealand being an unregulated market place for this technology, there are a number of manufacturers with systems which are designed for warmer climates, and have particularly poor performance in colder weather and therefore rely on inefficient back up as the norm. With Ecodan you can be assured that the performance delivered via our Power Inverter and Zubadan Systems will work throughout all New Zealand conditions.**** All units are rated at 2°C ambient, Zubadan units hold full capacity and 55°C output water down to -15°C.
As the need to be more energy efficient becomes a higher priority to us, we will see that air to water heat pump systems are the future of home heating, and remember the Ecodan System can also generate all your domestic hot water too. If your client likes the idea of a hydronic heating system, Ecodan is the energy efficient answer.
Wednesday 21st of November 2018
In New Zealand central heating is fast becoming the heating system of choice where whole home comfort is highly desirable. Whether it is underfloor heating, or radiators as used throughout Europe, both are becoming increasingly popular in the domestic market. So, the question must be asked, what is the best way to generate heat? Also, what factors are important to consider when choosing a central heating system for your client?
This is a big subject to cover, and addressing it means that we will have to challenge the way things have always been done by giving detailed attention to areas we often overlook.
These areas include the effects of the day to day weather on a home and if the insulation levels of the home mean that the energy use is higher than necessary.
Among other factors such as location and orientation, good thermal insulation reduces the effect of the surrounding weather on a home. By keeping it cooler in summer and warmer in winter, the need for cooling and heating is reduced.
Current statistics show that the highest consumers of energy in New Zealand homes are hot water (38%) and home heating (36%) which combined account for 74% of your energy use.
Finding the most efficient way to generate your hot water and heating therefore is an important point of consideration.
The Ecodan Range of air to water heat pumps are designed to deliver efficient, renewable heating and hot water for your home. Mitsubishi Electric are once again leading the way with the acclaimed Ecodan Range, bringing intelligent, high quality whole home heating to New Zealand.
Within the industry for air to water heat pumps there is some choice on the market however the performance of the units can vary significantly. A commonly used measure is the Coefficient Of Performance
(COP) which is simply the amount of electrical energy consumed compared to the system heat output. A heat source that is classed as renewable is a product that outputs at least 2.5 times the energy consumed.
For example, a COP of 1 : 2.5. A COP is a specific measure on a given day. So, if the outdoor ambient temperature is 15°C and the heat pump is putting a flow temperature of 35°C, it stands to reason that the COP on that day and time would read very differently to say an ambient temperature of 2°C and a flow temperature of 55°C. In this case the heat pump will need to work harder to pull heat from a colder ambient temperature and maintain a higher output.
What would be more accurate is a measure that rates the system seasonal performance known as Seasonal Coefficient Of Performance (SCOP), where the system is measured against year round outdoor ambient
However, these figures can be hard to find, so how then can you make an educated choice for a system that will meet your client's needs? I would suggest that if manufacturers indicate that their systems are not suitable for colder areas of the country, or if they are reluctant to publish performance at low temperatures, then this is a good indication that their systems perform poorly in colder temperatures.
This means a back up immersion heater will have to be used, compromising system efficiency and therefore increasing environmental impact and run costs.
Simply put – not all heat pumps are the same. In some cases, the performance can be so poor that you would save your client's capital expenditure and run costs if you installed a gas central heating system.
The Mitsubishi Electric Solution
With a range of integrated products, Mitsubishi Electric will be bringing central heating and hot water solutions to our lineup. Our hot water cylinders are high quality products – pre-plumbed, pre-wired,
low standing loss and using plate heat exchangers for high efficiency hot water generation.
The flow temperature controllers are the Fifth Generation (FTC5) Controllers, with unique self-learning settings for maximum efficiency, control and feedback with energy monitoring built in. All of course tied off with a single outdoor unit with the usual high efficiency and low noise you would expect from a Mitsubishi Electric unit.
New Generation Zubadan provides powerful heating in cold regions where most heat pumps lack in performance. Zubadan's rated heating capacity is maintained even in outdoor temperatures as low as -15°C, with guaranteed heating operation at -25°C outdoor temperature. That means Zubadan can be trusted to provide comfortable heating during severe winter months. Furthermore, faster tank heater times are achieved in low ambient temperatures compared to standard models temperature. Zubadan is available on our 8kW – 14kW models only.
State of the art energy monitoring and management of the Ecodan Heat Pump System means families now have the visibility and freedom to efficiently manage their overall household power consumption for heating and hot water. Energy monitoring means households can now easily take advantage of off-peak tariffs, giving them the ability to save even more on their power bill.

Having won the same award in 2015 and 2017, and as a runner up in 2016, Mitsubishi Electric is proud to be bestowed with this honour once again. Winning the most recent Readers Digest Most Trusted Brand Award cements Mitsubishi Electric as the brand that New Zealanders continue to trust to provide them with energy efficient, quiet, reliable performance and comfort when they need it most. Mitsubishi Electric Heat Pumps have always been designed with heating in mind, but our systems also keep New Zealanders cool all summer long. By focusing on warmth, Mitsubishi Electric Heat Pumps excel at what New Zealanders expect them to do – keep them warm in winter. A heat pump is a long term investment in comfort and health, so it’s imperative to invest in the best. Trust is built upon quality, reliability and integrity, all of which are core values of Mitsubishi Electric which reassures consumers that they are making the right decision on their investment. For over 19 years, Readers Digest have carried out this survey with consumers to find out what brands, products and services are important to them in motivating their buying decisions and, as we are creatures of habit, their long-term loyalty to a brand. Here at Mitsubishi Electric we pride ourselves on the products we sell and the Authorised Dealers we work with. We would like to take this opportunity to thank all of our Authorised Dealers for your loyalty over the years, as without you and your support, we could not have achieved this accolade. This award is a testament to our joint achievements in the heating and cooling industry, and we look forward to building on this trust and loyalty with New Zealanders in 2018 and beyond.
