A ground source heat pump unit is an electrically powered system that uses the natural energy stored in the earth to heat your home. It operates similarly to a refrigerator in reverse.
Just 2 metres below the surface the temperature of the ground is a fairly consistent 11-12 C.
This warmth can be captured using a pipe work system buried in a trench or borehole & can used as a reliable heat source to run central heating in the home. The ground source heat pump uses this freely available energy to provide low cost, low carbon high efficiency heating all year, irrespective of seasonal variations of air temperature.
A refrigerant circuit allows the temperature to be boosted to a useful level for the provision of heating & hot water in the home.
Ground source heat pumps are intended to be the sole source of heating & hot water but produce heat at a lower temperature to that of a conventional central heating system & so are better used with heat pump specific large radiators or underfloor heating.
The ground source heat pumps are suitable for a variety of properties and are designed to be the sole source of heating and hot water in the home. System heat pumps require a separate cylinder and can also be used with solar water heating. Combi heat pumps have an integrated cylinder.
For every single kilowatt of electricity used to power the ground source heat pumps, this system could generate four kilowatts or more in energy for your home.
