The new Mitsubishi Electric Climaveneta INTEGRA i-FX-Q2-G05 4 Pipe Multifunctional Heat Pump Chiller with low GWP refrigerant R513A

Monday 14th of September 2020
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.

More environmentally-friendly R513A has a GWP that is 56% lower than R134A refrigerant

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.

Next-generation VSD Screw Compressors and EC Fans maximise energy efficiency

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.

Full Inverter Technology ensures greater efficiencies at part load

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.

Improved seasonal efficiencies are achievable with variable water flow control

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.

Quiet operation for ultimate comfort

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:

  • CA for Class A efficiency (as standard)
  • SL-CA for super low noise with Class A efficiency
  • XL-CA for extra low noise with Class A efficiency

Reliable operation all year-round

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 W3000TE Controller and KIPlink Wi-Fi Interface enables total plant control from anywhere

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.

Lossnay Single Room Ventilation with Energy Recovery is now available with an in-ceiling ducted solution

Tuesday 7th of July 2020
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.

The benefit of fresh air

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.

Balanced pressure energy recovery ventilation

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

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.

Single Room VL100 Ducted Ceiling Mount Fresh Air Energy Recovery Ventilation

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

  • Up to 64% heat exchange efficiency
  • Low height 204mm
  • 100mm duct diameter
  • Lightweight and compact
  • Low noise operation from 25dB on low fan speed
  • Filter replacement notification
  • Air intake can be installed away from the unit in the most convenient location
  • Ideal for residential or small commercial applications with ceiling void or roof space

Single Room VL100 Wall Mount Fresh Air Energy Recovery Ventilation

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

  • Up to 80% heat exchange efficiency
  • Simple installation by drilling two 75mm diameter installation holes
  • Low noise operation from 25dB on low fan speed
  • Easy to clean filters
  • Ideal for residential or small commercial applications where there is no roof space

Energy recovery ventilation works all year round

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.

Ecodan Hot Water Heat Pump easy installation and commissioning

Tuesday 7th of July 2020
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.

Floor Dry Up Mode

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.

The control is in your hands with energy monitoring and system analysis

Ecodan controllers have several ways to analyse the system again to help the installer and homeowner / tenant.

Easy diagnosis with SD Card Analysis

The SD Card System Analysis will start recording the system including:

  • flow temperature
  • setpoint
  • outdoor temperature
  • flow rate
  • pump speed
  • compressor frequency
The data provides the installer with the opportunity to diagnose the system after installation and make fine-tuning if necessary to meet the customers’ requirements.

* SD logo is a trademark of SD-3C, LLC

Home automation system control

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.

Evaluate energy usage at a glance with Energy Monitoring

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 is the next-generation in hot water and space heating

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.

Hybrid VRF – The advantage of water

Friday 19th of June 2020
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.

Simultaneous heating and cooling with full heat recovery

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 economic hydronic heat recovery solution

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.

All the benefits of VRF with significantly lower global warming potential

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.

Hybrid VRF is the new VRF standard in New Zealand for both large and small applications

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.

HVRF key benefits

Minimise the need for leak detection systems

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.

Flexible design and modularity allow for a manageable phased installation

The small footprint and modular design means building owners can now take advantage of a manageable phased installation.

Regulated phase down of CO2 emissions

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.

Product Focus - Climaveneta INTEGRA Chiller

Friday 12th of June 2020
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.

INTEGRA is ideal for a variety of large-scale applications

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.

Simultaneous generation of heated and chilled water – all in one system

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.

Year-round heating and cooling you can count on

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.

Next-generation energy efficiency with heat recovery technology

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.

Climaveneta helps decrease your building’s carbon footprint

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.

Minimise initial investment and maintenance costs

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.

A smaller plant size to enhance the building’s usable space

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.

Designed to maximise efficiency at partial load

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 – the ultimate solution for any environment

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.

New City Multi R32 Hybrid VRF Delivers a System with a GWP 66% Less Than Existing R410A VRF Solutions.

Thursday 28th of May 2020
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.

R32 Hybrid VRF is the world’s only low GWP 2-pipe hydronic heat recovery system

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.

Water instead of refrigerant is at the heart of the indoor units

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.

All the benefits of VRF with significantly lower Global Warming Potential

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.

The complete solution for today’s modern buildings

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.

Combat the rising costs of R410A refrigerant

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 VRF standard

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.

The future-proof solution to meet changing environmental demands and corporate responsibility

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.

Case Study – Mt Ruapehu Ski Club

Tuesday 12th of February 2019
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.

The Challenge

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.

Ecodan Smart Energy Monitoring and Management

Monday 14th of January 2019
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

  • Consumed electrical energy for space heating, cooling and domestic hot water (kWh)
  • Delivered energy for space heating, cooling and domestic hot water (kWh)

Other Features
  • Daily, monthly and yearly data are stored and can be displayed using the main remote controller
  • External power meter and heat meter can be connected for accurate measurement
  • An SD card is included for storing usage data

Auto Adaptation

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.


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.

Ecodan – Why Water?

Monday 17th of December 2018
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.

Why Water?

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?

  • Water is abundantly available, non-toxic and non-hazardous.
  • Water can retain heat longer than most other substances.
  • It has a unique heat capacity; the presence of hydrogen bonds causes water to heat and cool slower than other substances.

The Benefits of Water

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:

  • Comfort levels are high because the whole house is heated.
  • There is no fan blown air so circulation of allergens and dust are reduced.
  • Condensation is minimised.

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.

The Concept

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.

The Future

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.

Ecodan Central Heating and Hot Water

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?

Consider how much energy your house uses and what the best ways might be to reduce this energy consumption

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.

Consider what the highest consumers of energy are in your home

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.

Coefficient Of Performance

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.

Seasonal Coefficient Of Performance

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 temperatures.

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.

Smart Energy Monitoring

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.

Auckland Food Show LX French Door Designer Series Competition Winner Announced!

Friday 5th of October 2018
In July, The Auckland Food Show saw thousands ascend to culinary heaven sampling the very best in food, wine and the latest in food preparation technology.

We were there again this year to showcase our sleek Multi Drawer Fridge Range of all shapes and sizes while having a little fun, with buyers simply guessing how many apples were in the Vitalight Humidity Drawer to be in to win a Mitsubishi Electric LX French Door Designer Fridge in either silver or black of their own. We are pleased to announce our winner was Harneet Kaur who won for herself a luxurious Black LX French Door Designer Series Fridge for herself! So, we thought it was time we caught up with her to see what she likes so much about her brand new LX French Door Designer Series Fridge! What drew you to our stand at the 2018 Auckland Food Show?
I really liked the Designer Series Fridges on display at the Food Show. Their colours were really different which captured my attention! What colour LX did you choose and why?
We chose the Black LX Fridge because we have always had silver or white fridges in our kitchen. By having a black fridge, it’s something a little different and non-traditional so makes a real statement in our kitchen. What kind of kitchen do you have?
Our kitchen is an open plan style with an island bench. What positive impact has the LX made in making your kitchen the hub of the home for entertaining and family dinners?
Our new fridge has given us plenty more storage especially for fruit and vegetables which is great! What is your favourite feature of the LX so far?
We love that it has a veggie drawer that is separate from the rest of the fridge giving us more room for more fruit and veges. Why is the Vitalight Humidity Drawer your favourite feature?
We now have a lot more storage in our fridge and the separate veggie drawer is a hit in our house. What is one feature you would recommend to anyone thinking of buying an LX Fridge for their home?
The larger capacity is great as you have more space to store more food. Congratulations Harneet, we are glad you enjoy your new LX French Door Designer Series Fridge!

Spring is a great catalyst for home improvements and renovations. It’s the time of year we start to look and think about how we can improve on issues that may have bothered us all winter long and get these fixed once and for all. Adding or updating your heating system as part of your home renovation plan is worth considering during this time, especially if you are contemplating installing a heat pump. Not only do heat pumps provide energy efficient heating during winter, but also cooling comfort throughout summer, ensuring your home investment is a worthwhile one. One of the most rewarding aspects of a renovation is transforming spaces by injecting your own personality into the home. Colour selection, accessorising and furnishing layouts all add to the overall design aesthetic, but successfully integrating large heating appliances into this carefully coordinated interior can often been a real challenge for home owners. The new Designer Series High Wall Heat Pump Range from Mitsubishi Electric has changed this. Available in a range of contemporary colours including Glossy White, Matte Silver and Rich Diamond Black, now you can truly reflect your design style; whether you want a bold statement or a sleek unassuming look.

If you are looking to make a bold statement, Rich Diamond Black will feel right at home on feature walls in soft blacks, dark grey and charcoal shades.

The Glossy White colour option lends itself well to interiors based around timeless neutral hues where an understated seamless look is desired.

The Matte Silver colour choice highlights the sharp edges of the slimline heat pump profile. Its versatile finish works well with the emerging colour trends for 2017 inspired by metals, stars and the cosmos.
But the Designer Series Heat Pump Range by Mitsubishi Electric is not just a pretty face. Underneath the award-winning slimline casing, a host of advanced features make this range cutting-edge with exceptional energy efficient heating and cooling comfort. 2 models have been awarded the Energy Star® Mark, making them some of the most energy efficient heat pumps available in New Zealand. With whisper quiet operation starting from a low 21 dBA (in Quiet Mode), the range is ideal for bedrooms and living rooms. Advanced filtration improves air quality, reducing airborne bacteria and allergens; ensuring the air in your home is not only comfortable, but clean. The 7-Day Controller that comes as a standard maximises energy efficient comfort and convenience, with the ability to program up to four time and temperature settings for each day of the week. The additional option of Wi-Fi Control means you’ll never have to return to a cold home again – no matter where you are. There is no longer a need to compromise when it comes to home heating. With superior energy efficient performance and looks to match, a heat pump doesn’t have to be an intrusive appliance on your home walls, but a statement in design, comfort and quality.

Centre stage to the open-plan home is the spacious kitchen, which features a glossy white finish that seamlessly transitions through to the bright sun-drenched deck. A subtle textured splashback, contrasting black granite island bench and contemporary flat-panel cabinetry make this kitchen the perfect fit for the WX Multi Drawer Refrigerator in White Diamond. Adding some warmth to the minimalism of this chic kitchen, the wooden flooring, copper light fittings and wooden-topped bar stools tie the space together in style. The owners have successfully combined design and functionality without compromise. It’s no wonder this family home on the hills of Wellington was considered among the best of new builds in New Zealand in this year’s Registered Master Builders House of the Year Awards.

Not only that, but the inverter compressor results in a super quiet dBA rating of 26 – a must have for open plan living spaces.

Think outside the box

Friday 23rd of October 2015
This was the design brief that inspired our engineers to go beyond the conventional, to push the boundaries and to challenge the status quo. The result, a refrigerator that is as individual as you are. Able to adapt to the lifestyle you lead, the foods you love and the way you like to cook and entertain. The Mitsubishi Electric WX is a flagship Multi Drawer Refrigerator that will take centre stage in your kitchen for years to come. At the heart of our WX range is our unique Multi Drawer Refrigeration concept. Different foods require different temperatures for ultimate freshness and longevity. Dedicated drawers provide separate temperature controlled zones that are specifically designed so you can accommodate all types of foods at their ideal temperature, so they will stay fresher for longer. Boasting a large capacity of 743L, VIP technology - a thinner, more efficient insulation that allows the WX743 to offer such large capacity while achieving thinner exterior dimensions overall - the WX743 unique multi drawer, multi compartment layout has been specifically designed to maximise space. Precise temperature management is achieved through a clever union of advanced inverter driven multi fan technology and 9 temperature zone sensors that are constantly monitored by intuitive control logic. Usage patterns are established over time and the Neuro Inverter Technology adjusts power levels for unparalleled energy efficiency. Inverter technology means not only has the WX been awarded the Energy Star Mark with an energy star rating of 3.5, but is also one of the quietest refrigerators in its size class at only 15 dBa. The striking glass flat panel exterior reveals a combination of French doors at the top followed by 4 speciality drawers. This layout specifically minimizes temperature fluctuations that are the norm with conventional single door refrigerators. The refrigeration compartment boasts tempered glass shelving, flexible storage options such as adjustable door pockets, and the latest innovation from Mitsubishi Electric, the Supercool Chilling Case, set between 3 and -3 degrees. In Supercool Chilling Mode, this speciality drawer is ideal for prolonging the life of premium cuts of meat meats and fresh fish without freezing it. The separate Versa Freezer Drawer enables food quality to be preserved for longer, without compromising on texture or original taste. With three modes, Supercool Freezing, Soft Freezing, and Hot Freezing, the Versa drawer is a helper for the everyday chef. Put your hot curry sauce straight into the freezer without damage using Hot Freeze, easily cut through frozen meat to make carpaccio with the Soft Freeze function, or maintain the texture of a high quality steak with Supercool Freezing. Standard freezing is also available, both in the Versa drawer and in the specific Freezer Drawer. Set between -22 and -16 degrees, the freezer drawer features a sliding tray ideal for frequently accessed or flat pack items. The sliding tray can be pushed back to reveal the freezer drawer which is ideal for bulky items such as ice cream tubs and frozen vegetables. The WX has a separate ice drawer for easy access to crystal clear, clean ice. It also boasts a Rapid Ice feature which is an added bonus for the entertainer. If guests unexpectedly pop in for cocktail hour you can speed up the ice making time for a single batch of ice, for cool drinks in no time. Mitsubishi Electric’s industry leading humidity drawer is now even more advanced with Vitalight Technology. An amber LED light installed at the back of the humidity drawer mimics the photosynthesis process, allowing fruit and vegetables to absorb energy from the light, maintaining vitamin C levels and keeping food fresher for longer. The sophisticated features offered by the WX743 are all accessible via an intuitive LED touch panel, which allows you to activate each function with ease. The WX743 is available now from selected retailers with an RRP of $5,499. There is no longer a need to compromise. Design, performance and functionality have seamlessly come together in the new range of Multi Drawer Refrigerators from Mitsubishi Electric.

Mitsubishi Electric Announced as Winner of the Canstar Blue survey for Heat Pumps

Friday 11th of October 2013
Mitsubishi Electric is very proud to have just been announced as the winner of the Canstar Blue customer satisfaction survey for heat pumps.

The Canstar Blue survey conducts research on New Zealand consumers to measure their satisfaction across a range of products and services. The survey found that Mitsubishi Electric heat pumps has the most satisfied customers, taking out the overall satisfaction award with a perfect five star rating.

"Mitsubishi Electric was highly rated by its customers in every category and was the only brand to receive a top score for quietness while operating" - Canstar Blue's General Manager Derek Bonnar. As well as quietness, we also received perfect ratings for energy efficiency, reliability and functionality.

Not only did we receive this fantastic news but we were pleased to discover that consumers now see heat pumps as a “must-own” appliance and almost 80% of those surveyed stated they are a must in any house they live in. With 45% of respondents stating their heat pump improved their health and 9/10 believing their home was drier and easier to heat as a result, it is easy to see why heat pumps are becoming so popular.
