By the work of the electric heater(3) operated by the midnight electric supply, the water in the heating tank(1) is heated. By the force of convection, the heated water located near the electric heater goes upward to the heat exchanging pipe(2) through the orifice(400) of the separator(4). Water descends from the top by the convection but it is hindered by the separator(4) and the amount of descending water is minimized. In this way, as the hot water is distributed from upward to downward, the heat exchanger located at the top gets heated quickly during the initial period of heating which enables the use of hot water even in the initial heating.
