Ground Source Heat Pump Technology
Ground source heat pumps use pipes which are buried in the garden or available land 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.
Heat from the ground is absorbed at low temperatures into a fluid inside a loop of pipe (a ground loop) buried underground. The fluid then passes through a compressor in the heat pump that raises it to a higher temperature, which can then heat water for the heating and hot water circuits of the house. The cooled ground-loop fluid passes back into the ground where it absorbs further energy from the ground in a continuous process as long as heating is required.
The length of the ground loop depends on the size of your home and the amount of heat you require. 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.
The pipework we use are specifically designed for ground source heat pumps. Collector pipes are brought together and connected to a prefabricated plastic manifold with regulating valves, integrated flow meters and a lockable manhole cover. We use an electro-fusion welding kit to fuse the joints together to ensure water tightness, through experience we find this system far more reliable and resilient than mechanical joints. The chamber would be dropped straight into the ground and means that there is no need for an inspection chamber to be built.
