Three outdoor capacities to choose from
The range is available in three sizes including a 14kW, 16kW and 18kW model. This much-anticipated product uses the Twin-Fan PUMY-P outdoor unit with a specially designed branch box. This connects to all our indoor units from our existing Multi Room Range.
Uses only one outdoor unit to minimise external clutter
Because the Ecodan System is able to join to that same branch box, domestic hot water, underfloor heating and radiators or a combination of all can be part of the same Multi Room System.
As a result, outdoor space is maximised as there are no additional big bulky outdoor units to worry about.
What are the key components?
The outdoor unit
The system uses our existing Twin-Fan PUMY-P outdoor unit.
The branch box
The PUMY-P outdoor unit is connected up with a specially designed branch box, with 5-port and 3-port branch boxes available which can be combined to allow connection of up to eight indoor units. Up to two branch boxes can be connected to the PUMY-P outdoor, enabling a wide range of configurations.
The indoor air conditioning units
Just like a traditional Multi Room System, any indoor unit from the Multi Room Range can be connected to the PUMY-P outdoor. This includes high walls, floor consoles, ceiling mounted and even ducted concealed units. This means the PUMY-P System is able to provide energy efficient air conditioning or heating of multiple rooms.
Furthermore, all units are run in either Heating Mode or Cooling Mode, with individual temperature control for each room.
The Ecodan Hot Water System
Either an Ecodan Hydrobox or Ecodan Packaged Water Cylinder System can be connected to the branch box. Designed with flexibility in mind, the system allows for various combinations to suit different applications including adding underfloor heating and radiators.
The illustration to the right shows a combined Mitsubishi Electric Multi Room with Hot Water System that features underfloor heating in the winter season and air-to-air cooling for the summer, whilst producing domestic hot water all year round.
How does it cool in summer and provide hot water?
To ensure the whole system is working as efficiently as possible, hot water demand is always prioritised. This means when the air conditioning indoor units are turned on in cooling and there is a hot water demand, hot water supply will override the cooling function of the air conditioners.
Prioritising hot water will continue until set temperature is reached. To mitigate this, it is important to set the time scheduler accordingly so water heating happens when cooling is not required at the same time.
For example, you can simply set the heat up time for when you are out at work or early hours of morning via the remote controller which can be located anywhere in the home.
Summer 2-in1 operation
In summer, air-to-air (ATA) cooling and domestic hot water (DHW) are utilised. Keep your room comfortable with ATA cooling during high temperature daytime. Heat pump operates to heat up water stored in DHW cylinder when ATA is not operated. The hot water can be utilised for shower and washing dishes during daytime.
The evolution in total home comfort is here
The ability to now combine a Multi Room Air Conditioning System with hot water heating is the ultimate in year-round, total whole home comfort.
