Lake and geothermal heat pumps

With a lake and geothermal heat pump from CTC, you can save up to 85 % on your heating costs. The heat pump utilises solar energy stored in the ground and in lakes. The energy utilised is free and eco-friendly, and contributes to a reduction of CO2 emissions.

To reach this energy resource, a liquid-filled collector hose measuring 200-500 metres is laid in the ground or in a lake. The circulating liquid in the hose is heated by the stored solar energy. The liquid passes through the heat pump where a compressor raises the temperature by means of a refrigerant and a heat exchanger in a closed system, after which the heat is distributed to the building’s heating system.
