This horizontal closed loop serves over 10,000 sq ft of heated space, domestic hot water, radiant floor, and hydronic air handlers. We installed a single WaterFurnace Envision to heat the 7400 sq ft home with four separate heating zones. A WaterFurnace E-Series water-to-water heat pump provides hot water which will heat the detached buildings and radiant floors. Both Geothermal Heat Pumps are connected to the same loopfield shown here. This home is insulated with closed cell spray foam which significantly reduces the heating loads. The system maintained 72 degrees throughout the house this December 2009. Based on the total amp draw (and $.072/KWHr), the system could run 24/7 (on high speed) for an entire month and the power bill would never exceed $260 for heating. Obviously it won’t run constantly, and the owner will enjoy even lower heating bills for this very large home.
