Using your geothermal heat system to also heat hot water provides significant cost savings. You won’t have to rely so much on that electric, natural gas, or propane water heater, so you’ll save on energy costs. In New Jersey and Pennsylvania, homeowners who use geothermal for their hot water needs find that hot water generation can cost about 80 percent less versus traditional water heating methods.
Excess heat is created by the geothermal heat pump in both heating and cooling modes, though more is produced through cooling because you’re trying to get rid of the heat, not bring more inside. Rather than depositing the heat from your home into the earth through the ground loop, that heat can be used to heat your water instead, allowing you to utilize that heat waste. Using a desuperheater in the summertime can create most or even all of the hot water you need around the house. During the other season, the desuperheater will still provide some of the hot water you need, but you’ll still need to use your primary water heating method.
