Ground source heat pump is a heating device that uses solar energy stored in the ground. The heat energy stored in the ground is collected by means of a plastic pipe or ground collector installed in the ground.

Land collector

 In summer, solar energy is stored in the upper layers of the earth's surface. In addition to direct solar radiation energy, the heat energy of rainwater and near-surface air is also stored in the ground.

 The soil can provide 30-60 kWh of energy per running meter of the collector per year.

 To heat 1 m² of floor space in a detached house, about 3 m of ground collector is needed, ie 3,6 m² of free ground.

In the case of a ground collector, a Ø40 × 2,4 mm PN 8 plastic ground heating pipe with a capacity of 0,97 l of geothermal fluid (denatured alcohol or ester aldehyde fraction) is usually installed in the ground.

 The soil collector is installed at a depth of approx. 1 meter (± 10 cm.) The distance between the parallel collector pipes must be at least 1 meter. The distance of the collector from the house is about 1,5 m.
