Heat pumps take warmth from our surroundings and compress it to provide heating and hot water for our homes. They are efficient because they typically generate three units of heat for each unit of electricity they use. 

Here is some general information about heat pumps. For further information, read the following pages.

 Air Source Heat Pump

Air-source heat pumps (right) work much like air-conditioning units running in reverse and can either use the warm air they generate to heat your rooms or to heat your hot water.

Ground Source Heat Pump

Ground-source heat pumps take heat from the ground by using coils buried in trenches (left) or from deep boreholes. As a result they are generally more expensive to install than air-source heat pumps.

Heat pumps work best in well-insulated properties and with underfloor heating systems. In poorly-insulated properties they have to work too hard and can end up being expensive to run.
