Established technology - the heat souce instalations

The principles of geothermal heating is simple, and aproved in many cases. The system contains of a heat pump, the geothermal probe or -collector and the heat source, the underground.

The heat pump works primaryly like a refrigerator: it compresses a heat-fluid, that before was led through the geothermal probe and hereby collected the geothermal heat (about 10 - 15 °C). By compressing the fluid, the temperature is lifted to a useable degree and then given over via heat exchanger to the heating circuit of the house.

This heating circuit can be planned as a conventional low-temperature underfloor-heating. All components are of improven technology, service-reduced and reliable. In the house, space is required only for the heatpump and additional installations for water-heating. Chimneys, oil-tanks and combustible tubes can be avoided.

Geothermal probes: less space - more eficiency

The geothermal energy usually is lifted with 50 - 100 m long probes, containing double-u- tubes. in These probes a water/glycole mixture circulates, that transports the earths heat to the heatpump. These circuits can be installed under the basement of a building and can also be combined with pile foundations.

Being installed professionally, a geothermal probe can have a live-span of about 100 years. The most important advantage is the high efficiency and the independence of winterly temperatures. Geothermal probes are ideals for house owners that:

  • do not have much garden space
  • give importance to a high effective system of heat extraction
