Heatpumps

Solar heat is stored in the surface layer of the soil. Using that energy for heating is an ideal way for heating houses with large plots. The amount of energy that can be extracted is greatest in soils with high water content.

The subsoil temperature does not change that much over the year if it is measured at a depth of 1 metre or more. Heat pumps pump a chilled water/brine solution though a network of buried small diameter polyethylene pipes. This water picks up heat from subsoil surrounding the pipe and returns to the heat pump at a higher temperature. Where the solution is chilled again, it thereby extracts the energy picked up in the pipes. The heat pump converts this low-grade energy to hot water, which is then used for heating.

Also down in the bedrock there is a source of heat that stays at practically the same temperature all year round. Using heat from the rock is a secure, safe and environment-friendly way of heating all types of buildings, large and small, public and private.

We use a full range of heat pumps including NIBE Heat Pumps. These units cover a wide range of applications from domestic to industrial.
