How a ground source heat pump works
A buried pipe circuit absorbs heat from the ground. The heat pump raises that temperature so it can supply the home's heating system and hot water cylinder.
What installation involves
The ground array can be installed in horizontal trenches or vertical boreholes. The right approach depends on available land, access, ground conditions and the amount of heat the property needs.
Start with the property
A useful assessment looks at heat loss, insulation, radiators or underfloor heating, hot-water demand and the space available for equipment. Warmaway can help you compare this with air source and other heating options.
