Ground source heat pumps (GSHPs) use pipes which are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home.

A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe, called a ground loop, which is buried in your garden. Heat from the ground is absorbed into the fluid and then passes through a heat exchanger into the heat pump. The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year.

The length of the ground loop depends on the size of your home and the amount of heat you need. Longer loops can draw more heat from the ground, but need more space to be buried in. If space is limited, a vertical borehole can be drilled instead.

  • Can earn you up to £29,500 with RHI payback. These are in payments spread across over 7 years at up to £4200 a year.
  • They are very efficient. Just 1kW of energy input can give you up to 3.5kW of energy output.
  • The carbon emissions are also low which helps keep them environmentally friendly.
  • There’s no need to store or reorder fuels such as oil or LPG which can cut cost and save storage room.
  • They are a long established, high quality product which uses proven technology so everything will run smoothly.
  • Finally, they can save up to 40% on heating and hot water bills; pretty impressive if you ask us!
