Ground loops

The productiveness of ground loops is mainly affected by the consistence and the specific humidity of the ground. Solid and humid grounds make up better heat sources than dry and sabulous ones. Above all, the ground regenerates itself through downcoming rainfall. 

Therefore, the surface must not be covered with buildings or be sealed in any other way!

Horizontal ground loops require more space. The ground loops need about 1.5 to 2.5 times of the heated living area. This area has to be without any buildings and must not be sealed so that the ground collector can be run in a depth of about 1.2 to 1.5 meters.

In development areas, it is relatively easy to install ground loops during the construction period by removing the ground at the reqired space. The removed ground can be refilled after laying of the loop. The loop can also be layed in ditches with the advantage that not too much ground has to be removed. If both types cannot be applied, there is the possibility of making vertical boreholes.
