Freeze in winter and sweat in summer
With the geothermal heating plant and geotechnology, Sockerhusen 1 & 2 and Geijer will take advantage of the earth’s heat and cold. This is an extremely cost-effective and largely climate-neutral heating alternative. During winter, heat is extracted from the bedrock where a circulating liquid in a closed system is heated by the groundwater (at about 300 meters depth). As the summer begins, the stored cold has been collected as “freezing” and the rock and can be used to regulate the temperature in your house.
Stored rock heat and cold for a perfect indoor climate
Generally, there are two different ways to utilize geo-energy for heat and cooling. A borehole storage means that the majority of energy wells are drilled in a defined area that forms the energy volume. An aquifer system is suitable in water-rich areas and is often used for larger buildings such as hospitals, airports or other large facilities. The geo-energy / geothermal principle is simple. During the winter, heat is extracted from the rock or groundwater and the bedrock is cooled down a few degrees. As the summer begins, the stored cold has been collected as “freezing” and the rock or groundwater gradually warms up and becomes the heat source next winter.
