Ground source heat pumps use pipes buried in the garden to extract heat from the ground. This is usually used to warm water for radiators or underfloor heating systems. It can also be used to pre-heat water before it goes into a more conventional boiler.

Beneath the surface, the ground stays at a constant temperature, so a ground source heat pump can be used throughout the year – even in the middle of winter.
The main benefits of ground source heat pumps include:
* Reduce your CO2 emissions: on average a ground source heat pump could save around 540kg of carbon dioxide every year when replacing an oil boiler.
* Eliminate your fuel bills: ground source heat pumps run on electricity, so there’s no need to pay for gas, oil or solid fuels to heat your home.
* Cut down on wasted electricity: heating your home with a ground source heat pump is much more efficient than using electric radiators.
