ABSTRACT:
An electric water warming system comprises a water storage tank of substantially cylindrical to be installed in a vertical fashion, a water feed pipe connected to a bottom portion of the water storage tank for feeding water thereinto, a hot water flow-out pipe connected to a top portion of the water storage tank for flowing out hot water therefrom, and a heating means disposed in the water storage tank at a portion relatively near the bottom portion of the water storage tank. The temperature of the hot water in the water storage tank is controlled by a control means including a hot water temperature sensor. A by-pass pipe is further connected to a side wall of the water storage tank at a portion relatively near the top portion of the water storage tank, and a three-way valve is assembled at a portion at which the by-pass pipe and the flow-out pipe are joined. The three-way valve acts so as to select the by-pass pipe and the flow-out pipe in accordance with a state of the hot water in usage thereof so that the late-night power as well as the daytime power can be effectively utilized.
