The groundwater is naturally purified with no biological and organic substances, unlike surface water that needs chemical and mechanical purification methods.

When establishing a groundwater well, we drill down to below the groundwater level. With large gravel deposits above the bedrock, there are often good opportunities for laying down a loose well. Pipes with filter pipes in the bottom are set to a suitable level below the ground water level, and the pump is mounted in the well.

If the groundwater level is below the bedrock surface, a bedrock well must be drilled. The groundwater is supplied to the borehole via cracking systems in the bedrock. In the same way as a loose-gas well, a pump is placed at a suitable level in the well below the groundwater level.

Utilization of primary heating for housing and commercial buildings.

An energy well utilizes the heat energy in the bedrock. This is a renewable resource that will always be available.

An energy resource is a one-time investment and an environmentally friendly measure that takes up little space and causes minor intervention on the property.

In an energy well, the water in the borehole is used as a contact medium between the bedrock and a heat pump circuitry mounted in the well. During this cycle there is a liquor-water mixture that, in winter, is heated by the water in the well and pumped to the heat pump where the liquid mixture releases the heat for heating. On hot summer days, the plant can give a cooling effect, as the liquid mixture is heated by the heat of the house and also cooled down in the well.

Energy wells can be established in connection with large buildings and industrial and residential complexes as well as in connection with detached houses.
