Domestic hot water is available with the use of a heat pump for pennies a day or even free. A hot water desuperheater is a heat exchanger built into the heat pump and is designed to remove high temperature heat from the refrigerant gases. A typical hot water desuperheater will generally provide 120° F water and can supply most of the domestic water needs depending on the amount of consumption. In buildings with larger requirements for hot water, ECONAR builds heat pumps that will provide hot water savings in commercial and industrial applications.
