ABSTRACT:
A control unit for controlling the temperature of a domestic water supply, comprising a temperature sensor for inserting into a water tank so as to produce a sensor signal representative of actual water temperature in a region of the temperature sensor and an electrical immersion heater for inserting into the water tank and energized by a source of electrical power. A setting device is adjusted by a user for setting a desired water temperature and producing a corresponding set signal, and a controllable switch is connected between the source of electrical power and the electrical immersion heater, and is responsive to the sensor signal and to the set signal for closing if the actual water temperature is lower than the desired water temperature and for opening if the actual water temperature is greater than the desired water temperature.
