The source for the energy extracted by a Greentec Heat Pumps is usually the ground arround the property. one option to extract this heat is to use a
goe-thermal bore hole. This is where a series on small diameter bore holes are created to a depth of 200 to 400 meter, depending on ground conditions. Pipes are then placed into the bore hloes and connected to the system.

The benfits of geo-thermal bore holes is the reduced amount of ground work required for the system.
