ABSTRACT:
There is disclosed a heat pump water heater with supplemental heat supply wherein the heat pump is turned on when water has cooled below a predetermined temperature, and is turned off when the water has been heated to a predetermined temperature. In the event frost begins to form on the surface of the heat pump evaporator, the heat pump is turned off and the supplemental heat supply turned on automatically. This condition prevails until the water has been heated to a predetermined temperature, at which time the supplemental heat supply is turned off.
