The BioClina ground collector is a prefabricated surface collector that has been used very successfully since 2002 for the efficient tapping of the ground as a heat source using brine/water heat pumps.
How does a ground collector work? Surface collectors supply the necessary geothermal heat to the heat pump heating system. The brine in the ground collector extracts the heat from the ground and transports it to the heat generator, the heat pump. In this way, surface collectors supply the necessary geothermal heat to the heating system.
The centrepiece of the ground collector is the capillary tube mat, which is used here as a surface heat exchanger. The capillary tube mats, which are laid horizontally at a depth of approx. 1.20 metres, are connected to a heat pump. The collector can be positioned individually on the property, whereby an area of 16 m² is required per collector circuit.
If possible, the area above the collector array should not be built on or sealed in order to ensure optimum regeneration of the soil. The area can be planted with shallow-rooted plants.
Thanks to their special abilities as high-performance heat exchangers, the extraction area on the property can be reduced by up to 50 % when using capillary tube mats compared to conventional single-tube surface collectors.
