Air Source Heat Pumps

What are Air Source Heat Pumps?

Air source heat pumps are renewable energy products which extract heat from the outside air. It can extract heat from the air even when the outside temperature is as low as -15 °c

How does it work?

Air source heat pumps move energy rather than creating it. Air pumps are very simple and not unlike any domestic refrigerator.


The main components in the heat pump are the compressor, the expansion valve and two heat exchangers (an evaporator and a condenser)

A fan draws the outdoor air into the heat pump where it meets the evaporator. This is connected in a closed system containing a refrigerant that can turn into gas at a very low temperature. When the outdoor air hits the evaporator the refrigerant will turn into gas. 

Using the compressor, the gas reaches a high enough temperature to be transferred in the condenser to the property's heating system. At the same time the refrigerant reverts to liquid form, ready to turn into gas once more and to collect new heat.

Using an inverter-driven heat pump compressor, the system can be regulated so that heat output matches the exact capacity required at any given time. This means the heat pump will only use what is needed, making it highly efficient.

What maintenance is required?

An annual service is recommended to ensure all parts of the unit are working properly. A regular serviced unit will run more efficiently and help keep fuel bills down.
