GRD - applicable where other systems fail

The company Winter from Fürth in Germany had decided to replace the aging electro heating in their residential and business premises and thus had closely been watching the market for geothermal heat extraction for more than two years. Provision was made for applying a geothermal heat extraction unit with a refrigerating capacity of 20 kW. To achieve this capacity bores of 400 m length all together were necessary.
