Geothermal Heat Pump and Free Cooling

Collect stored solar energy from the ground to heat your property in winter or use the rock to cool it in summer. With a ground source heat pump, you pay for about a quarter of the energy your property needs. Depending on the conditions, you can expect a roughly halving of your heating costs. If the property has a cooling need, it can be met virtually free of charge by investing in boreholes that are cold in the summer.

That's how much we've saved with geothermal heating and free cooling

How does Geothermal Heating Work?

Geothermal energy uses the stored solar energy in the bedrock and is a technology that replaces district heating as the primary heat source.

A number of holes are drilled into the bedrock, to a depth where the temperature is constant at 6-8°C all year round. Collector hoses are used to pump a coolant liquid into the hole, where it is heated by the rock and then pumped back to the heat pump. Using a compressor and heat exchanger, the energy is recovered in the pump and distributed to the building’s hydronic heating system. The now-cooled brine is pumped back into the rock to recover new energy.
