With minimal electricity, air source heat pumps transfer energy from the air into heat to provide you with all your central heating and hot water needs.
There are three main components that make up this technology. The evaporator (the first heat exchanger), compressor and condenser (the second heat exchanger) work together using the outside air to create heating and hot water.
The air source heat pump absorbs air through fins at the back of the unit. There is energy in the air that can be used by an air source heat pump at temperatures as low as -20°C.
Once in the heat pump it causes the refrigerant to evaporate.
The compressor increases the temperature of the refrigerant to a usable temperature.
Heat is then transferred via a condenser which acts as a second heat exchanger. This in turn causes the refrigerant to turn back into a liquid within the condenser.
Lastly, the colder water from the central heating passes through the heat exchanger and withdraws this heat for use in radiators or underfloor heating and hot water.
