Geothermal energy

Inexhaustible. Cost-effective. Sustainable.

You too can use free energy out of the ground to heat and cool buildings.

 
 

What is geothermal energy?

Geothermal energy is the thermal energy stored in the ground which is constantly being recharged like a battery by heat from the Earth's core and - close to the surface - by solar radiation. In our part of the world, the Earth maintains a constant temperature of 8 to 12°C at a depth of 10 metres all year round.  

This temperature level is suitable for both energy-saving building heating with heat pumps and also building cooling.
Through the use of geothermal energy, modern heat pumps convert one kilowatt hour of electricity into up to four or more kilowatt hours of thermal energy. Using a geothermal heat pump thus also saves considerable amounts of fossil energy and significantly reduces CO2 emissions.

Did you know?

A brine-water heat pump saves 78% of CO2 compared to oil-fired heating.

The sun provides 2850 times the energy required in the entire world.

There are already approx. 300,000 geothermal Systems in Germany.
