This unit draws excess superheat from the refrigerant and exchanges this heat with water circulating to and from the hot water tank. In many areas, the unit will provide approximately 50% or more, of domestic hot water needs. The unit can also easily be modified to heat a hot tub or swimming pool, as well as provide heat for a hydronic (in floor) heating system and other heating and cooling distribution systems.
