Fernwärme Haag uses water from a depth of 2000m for the purpose of heating parts of Haag am Hausruck and Geboltskirchen (AUT, UpperAustria). We pump 86°C hot thermal water from 460m below surface and distribute directly through our entire heating network. This way we supply clean, renewable energy to over 300 customers and give the cooled down water back to earth via the Trat 9 reinjection well. This envirometly friendly way we provide comfort: clean energy, reliable district heating distribution stations, billing and system services – everything from a single, regional source!
