Ground Sourced Heat Pump

Ground source heat pumps use the temperature of the soil under earth. The antifreeze-water mixture is circulated throughout the pipes which is placed vertically or horizontally underground. Antifreeze-water mixture extracts heat of underground and transfers this energy to the water which is circulated in the heated ambience such as radiators, under floor heating pipes or the domestic hot water. The length of the pipes to be placed underground changes due to the proper area and the amount of necessary heat capacity. The longer the pipes are, the greater amount of heat transfer can be provided.

Mostly horizontal piping is used. However if you do not need available land vertical piping is preferred. If vertical piping is used, 100m depth has to be reached, that’s why vertical piping is more expensive then horizontal one. In addition, the moister the soil is, the easier the heat transfer is.
