Ground Source Heat Pumps
A Ground Source Heat Pump can heat your home and provide you with hot water in place of a traditional gas or oil fired central heating boiler. The heat pump collects solar heat naturally stored in the ground outside, this is absorbed into water flowing through collection pipes buried beneath the surface.
By collecting a large amount of low grade heat from the ground and concentrating it into a smaller amount of high grade heat the heat pump can supply the heat you need. The water circulating around the ground loops is pumped through the heat pump, the heat pump takes a small amount of heat from it and so the water coming out of the heat pump is about three degrees cooler. This goes back underground where it gets warmed up again. The heat taken from the ground loop is concentrated inside the heat pump and used to heat up the water flowing around the radiators or under floor heating pipes and to heat the hot water tank.
