  • Patent number: 4543468
    Abstract: A control system for an electric domestic water heater operatively associated with an external heat source, such as a heat pump, and including a water storage tank having an internal electric heater unit controlled by a tank thermostat responsive to the water temperature in the tank. The control system maintains the tank heater unit effectively turned off and turns the external heat source on in response to an indication from the tank thermostat that there is a demand for hot water. The control system turns the external heat source off in response to an indication from the tank thermostat that the demand for hot water has been satisfied. The control system may include devices, such as an evaporator thermostat, high pressure cut-out switch, etc., indicative of the condition of the external heat source for turning the external heat source off, turning the tank heater unit on and maintaining the tank heater unit on until the demand for hot water has been satisfied.
