The sun is an energy source whose heat is stored in the earth. It is this stored heat that is converted by our heat pumps into heating and domestic hot water for your home.

Part of the heat from the earth is fed into the heat pump through a heat-transfer medium, and converted into higher temperatures for your heating.

In the process, the heat pump produces far more energy than it consumes. For every kilowatt-hour purchased your receive a free contribution from nature comprising a further three to five thermal kilowatthours, which are available as heating capacity.

A heat pump for earth or water can be used anywhere, producing pleasant and environmentally friendly heat for your home, even on the coldest winter days.
