Ground source heat pumps operate as common air-water heat pumps, with the difference that pump or reject heat from and to the ground instead of to and from the air.

The transfer of heat from the premises to the ground is made ​​with special water pipes buried in an appropriate manner within the soil.

At the depth of the buried pipes, soil temperature is about 16-18 °C throughout the whole year. We all know that the air during summer can reach temperatures of 40 °C and during winter 0 °C or lower. Therefore, the ground is relatively cool in the summer and relatively warm in winter. Precisely for this reason, ground source heat pumps have a higher seasonal coefficient operation of performance compared to the air-water heat pumps.

A ground source heat pump is in the form and size of a household refrigerator, while works noiselessly. For this reason, it can be placed at any interior space.

The use of ground source heat pumps is indicated in hotels, natatoriums, schools, kindergartens, clinics and multifamily houses over 500sq.m.
