The Woferlgut sports camp decided to use the BES system for the construction of a state-of-the-art sports and performance centre with a luxury spa area. PRIME multi-source heat pumps are used, which use groundwater and a geothermal storage tank installed by BES as sources. The system is completed with a thermal solar system. (You can find a time-lapse video of the geothermal storage tank installation at www.bes-eu.com/system)
