Air Source

Air source heat pumps are intended to be the sole source of heating and hot water production for the home. This gives homeowners the option of removing their existing boilers etc. Some heat pumps can be configured to run alongside solar thermal collectors.


Heat pumps use similar technology to that employed in domestic refrigerators or freezers, but in reverse.


An air source heat pump works by extracting low-grade heat from the air outside but where a refrigerator rejects heat from the contents to keep it cool, a heat pump will use it to heat water and provide heating.

Ground source heat pumps use the heat stored in the ground to generate heat for your home, it works in a similar way to the air source. With a ground source heat pump the supply temperatures are more consistent and therefor they work more efficiently.


The only energy used by Ground Source Heat Pump systems is electricity to power the pumps. Typically, a Ground Source Heat Pump will deliver 3 or 4 times as much thermal energy (heat) as is used in electrical energy to drive the system. For a particularly environmental solution, green electricity can be purchased.


Ground Source Heat Pump systems have been widely used in other parts of the world, including North America and Europe, for many years. Typically they cost more to install than conventional systems; however, they have very low maintenance costs and can be expected to provide reliable and environmentally friendly heating for in excess of 20 years.
