George Clarke is a passionate advocate of

design excellence and high levels of quality

in the construction industry.

The way we design, build, heat, power and recycle our homes needs to change,

and change quickly, and renewable heating is an important part of our future.

I’m therefore delighted to associate myself with Ecodan, the market-leading

brand of heat pumps built here in the UK and which can help reduce energy

bills and lower emissions for almost any home.

How do Ecodan air source heat pumps work?

What is the vapour compression cycle?

At the beginning of the first phase the refrigerant is a cold low pressure liquid

Ecodan heat pumps harvest, upgrade and move heat from

one location to another.

Refrigerant passes through the evaporator and is exposed to the heat energy of the outside air. As the air flows over

the evaporator coil, this heat energy is transferred to the refrigerant, causing it to pressurise into a warm vapour.

To achieve this, the vapour compression cycle is used, which has the ability

This warm vapour then enters the compressor where its temperature increases as a result of the compression

to take low temperature renewable heat from the environment and raise it to

process and turns into a hot gas.

usable temperatures capable of handling the space and water heating

loads required in buildings.

Hot refrigerant gas passes through the condenser (plate heat exchanger) and transfers its heat energy into the

(cooler) water side that is connected to the primary water circuit. The heated water in this circuit is then used to

heat up a hot water cylinder inside the property. Due to this energy transfer, the passing hot refrigerant gas cools

and transforms back into a cool vapour.

Although the refrigerant vapour has cooled, in order to return the refrigerant back to its initial state, it is passed

through an expansion valve. This lowers the pressure of the cool refrigerant vapour and transforms it back into a

As the refrigerant boils at -46ºC, there is still plenty of energy in the air on a cold day to make the process work.

*As independently tested by BSRIA based upon BSEN14511 Part 3 standard rating conditions. Due to the method of operation, the

performance of heat pumps will vary based upon the temperature of the heat source and the requirements of the heat delivered. The

BSEN14511 testing relates to the heat pump performance only and not the entire heating system.
