Geothermal heat pumps can be used for more than just heating and cooling your home. A geothermal heat pump can be used for hot water, snow melt, ice-making, and even pool heating. Using a geothermal heat pump for hot water heating can actually make your heat pump even more efficient!What you'll needIf you plan on using your ground source heat pump for hot water you'll need to add a desuperheater. A desuperheater captures the heat that is naturally lost by running the heat pump. As efficient as a geothermal heat pump is, there is a small amount of heat produced by the pump that is not used to heat your home. A desuperheater captures this expended heat and pumps it to the hot water tank.Aside from the desuperheater you will not need any additional components. The desuperheater connects directly to the hot water tank drain.Even More SavingsBy using a geothermal heat pump for hot water heating you will greatly offset your current water bill costs. A geothermal heat pump can provide enough heat to your hot water tank to prevent the boiler or watermark from running just to maintain the heat in the tank.Adding a desuperheater will not diminish the efficiency of your geothermal heat pump, nor will it cause your heat pump to work any harder. For most homeowners, utilizing a geothermal heat pump for hot water is a no-brainer.
