Ground source heat pumps are also known as geothermal systems that extract and transfer the natural heat from the ground into a property, which provides the energy required for both hot water and heating requirements.
Air source heat pumps have the advantage of not requiring boreholes or trench excavations on adjoining land. They work in a similar way to ground source heat pumps, but by extracting natural heat from the air via a surface absorber fitted outside the property.
Air to water Heat PumpsAir exhaust heat pumps extract the air from a ductwork system which is connected to the warm areas of the building.
