Terraced houses, Reinmattstrasse, 3011 Bern

DESCRIPTION:

In Bern, tradition meets innovation. Three historic terraced houses have been equipped with geothermal probes. The developers opted to replace the old gas heating systems with environmentally friendly heat pumps in order to reduce energy costs and contribute to sustainability.

Three GEROtherm^® DUPLEX probes of 170 metres each and two GEROtherm^® VARIO probes of 300 metres each were used for the probe field. Pressure loss in the conical, pressure optimised GEROtherm^® VARIO geothermal probes is significantly reduced in comparison with a corresponding PN20 geothermal probe, resulting in lower energy requirements for the circulation pump.
