Purpose
In connection with heating needs in the building, wells are drilled to cover the building's need for heating, the project by an external supplier
Execution A well park has become dry with the use of a drilling rig and compressor, 8 wells in total. Wells are drilled with 139 casing pipes down to 1 meter in good rock, cast tightly so that groundwater does not enter, then down to the desired depth. The collector is then set in the desired dimension, filled with liquid/alcohol that will draw heat out of the rock using the heat pump that drives the liquid around the system. Hoses run from well tops to a sump, and on to a technical room with a butterfly valve
