Air source heat pumps take air from the outside which is absorbed and passed through a heat exchanger. After going through a refrigeration system the heat is then compressed and concentrated which creates temperatures that are usable as hot water and space heating. Basically the heat pump works in the opposite way to a fridge/freezer.

A ground source heat pump works the same way as an air source heat pump but instead of getting the initial heat from the air it collects the heat from the ground. Once you get below the frost line below ground the temperature is quite consistent throughout the year making ground source heat pumps highly efficient. When coupled with underfloor heating ground source heat pumps can produce one of the most energy efficient heating systems available. Loops or runs of pipe are laid in trenches and then back-filled. This pipework then collects the heat from below ground and takes it to the heat pump.
