Let's rethink heating

Geothermal energy is an untapped renewable energy source with great potential. Originating from the Earth’s interior, geothermal energy can be used for district heating. Essentially, it entails harnessing subsurface heat – similar to how we harness energy from the sun and wind today – to serve as a sustainable heating alternative to fossil fuels such as coal and gas.

Radiators with green heating

In the geothermal plant, the heat from the subsurface is transferred to the district heating grid in a closed circuit: First, the hot water is pumped up from the subsoil. Then, the heat from the water is transferred to the district heating system. If the water from the subsoil is not quite hot enough for district heating, heat pumps deliver the final degrees. Finally, the cooled water is pumped back into the subsoil.
