The New Power Multi Series – PUMY-SP
Tuesday 13th of August 2019
An exciting new addition has been made to the Multi Room lineup with the new single fan PUMY-SP. Replacing the MXZ-8C140/160 Power Multi units, this system now offers an easier installation, a wider range of installation possibilities, improved energy efficiency and an unobtrusive, compact size.
Simple and Discrete Design
The single fan unit offers a low height profile and small footprint, keeping outdoor spaces uncluttered. The compact design fits into narrow outdoor areas found in applications like condominiums and offices. And with a light weight, transportation and installation is easy.
Energy Saving with High COP
The Power Multi Series provides superior energy efficiency with a high COP of over 4, so you get over 4kW of heat energy output for every 1kW of power input.
Flexible Installation Possibilities
With an external static pressure of 30Pa, the PUMY-SP can be installed in a wider range of locations such as on balconies in high-rise buildings or spaces near louvers. The compact size also allows installation in locations that would otherwise be unsuitable. Piping workability is greatly improved with piping pullout locations in four directions, providing expanded piping layout flexibility.
Guaranteed Heating Down to -20°C
The Power Multi Series is able to provide heating right down to -20°C outdoor temperature, so you stay warm on even the coldest days.

The noise level of the unit can be reduced by up to 10dBA, allowing the unit to operate during the night in a residential zone without disruption to your neighbours.
Potable Hot Water Solutions
Monday 12th of August 2019
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.

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.
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)
- 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
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.
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.
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.
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.
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?
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.
