What is a Ground Source Heat Pump?

Ground source heat pumps (GSHPs) extract heat from the ground using pipes buried in your garden. The ground temperature stays constant at 10-15°C year-round, making GSHPs incredibly efficient even in winter.

GSHPs are 300-400% efficient, meaning for every 1 kW of electricity used, they produce 3-4 kW of heat. They're the most efficient heating technology available and can reduce your heating bills by up to 70%.

How Ground Source Heat Pumps Work

1

Ground Loops

Pipes buried 1-2m underground collect constant ground heat

2

Heat Exchange

Antifreeze fluid absorbs ground heat and returns to pump

3

Amplify Heat

Heat pump increases temperature to 45-55°C

4

Warm Home

Heat distributed via underfloor or radiators
