Abstract
A water heating system having an electric heater and an automatic temperature control system having high dynamic response for supplying water on demand at a substantially constant, controlled temperature is provided. The device includes a heat exchanger, and inlet diverting pipe, an outlet diverting pipe, a mixed flow pipe and a temperature control system. A tuning valve on each of the inlet flow diverting pipe and the outlet flow diverting pipe controls the ratio of heated and unheated flow entering the mixed flow pipe. The temperature control system controls the temperature of the water by establishing an empirical, monotonic relationship between the current applied to the heater and the temperature of the mixed flow.
