ABSTRACT:
Increased efficiency for heating water with a conventional electric water heater tank is obtained with a unit which may be placed next to the side of the hot water tank and readily connected thereto. More specifically, the preferred unit fits along the vertical wall of the conventional water tank and, to this end, includes a narrow upright housing with an inner arcuate wall positioned closely adjacent the cylindrical wall of a water heater tank. The preferred unit has therein a refrigeration apparatus comprising a condenser at the upper end of the unit and closely adjacent the upper end of the tank, a compressor directly therebelow, and an evaporator which withdraws heat from air circulating therearound in a lower chamber. A water circulation system for circulating water through the unit withdraws water through an intake conduit connected to an existing port in the lower end of the tank and pumps water through tubing into a heat transfer relationship with the heated condensed refrigerant to absorb heat therefrom in the condenser unit, and the heated water is returned to the tank through a return conduit connected to an existing safety valve port in the upper end of the tank.
