These pumps collect energy from the ground and make use of the stable all year ground temperature. At one metre’s depth, the average soil temperature in the UK remains consistently at 10–13°C.
Pipes are sunk into the ground via a horizontal loop, borehole or even a deep lake and the water and environmentally friendly anti freeze (Glycol) which runs through the pipes, absorbs the thermal energy from the ground as it passes through.
This is then circulated through the heat pump where it is converted into useable energy to heat your home or hot water.
