ABSTRACT OF THE DISCLOSURE An automatic hot water supply apparatus produces and supplies hot water by mixing, with a hot water/cold water mixing valve, hot water supplied from an instantaneous water heater unit through a hot water supply pipe and cold water supplied through a cold water supply pipe. The auto- matic hot water supply apparatus includes a flow rate con- trol valve actuatable by an electric actuator, and a flow rate limiting unit responsive to a hot water temperature setting, or a season setting, or a detected hot water temperature, for varying the flow rate of mixed hot water. The electric actuator is controlled by a signal from the flow rate limiting unit to operate the flow rate control valve in order to solve the problems of a low water tempera- ture during the winter, an excessive hot water flow rate, and a low instantaneous water heater unit capability, so that the automatic hot water supply apparatus can supply hot water at a desired temperature.
