Gundersen Health System's Geothermal Heat Pump

As part of its plan to achieve energy independence, Gundersen Health System installed a 300-ton heat pump along with 156 wells buried about 400 feet underneath a parking lot. The system takes advantage of the moderate temperatures underground to improve efficiencies of HVAC equipment.
