<p>PURPOSE:To get a high hot water feeding pressure by a method wherein an electric valve for a water feeding is connected to a water feeding pipe connected to a bottom part of a hot water storing tank, another electric valve for feeding hot water is connected to a hot water storing tank top part, a releasing pipe is arranged in the hot water storing tank, and both a releasing solenoid valve and a releasing valve are arranged in the releasing pipe. CONSTITUTION:A water supplying pipe 3 is provided with an electric valve 4 for feeding water. Hot water feeding pipe 5 is provided with an electric valve 6 for feeding hot water. A releasing pipe 7 is provided with a solenoid valve 8 for a releasing operation and with a releasing valve 9 (a set pressure of 0.9kg/cm<2>). When a heater 2 is electrically energized, the solenoid valve 8 for the releasing operation is opened and upon completion of an electrical energization of the heater 2, the solenoid valve 8 for the releasing operation is closed. In the event that the heated hot water is to be utilized, the hot water feeding switch of the hot water feeding operation part 10 is depressed, the electric valve 6 for feeding hot water is opened through a controller 11 and subsequently the electrical valve 4 for feeding water is opened with a certain delay time. With such an arrangement, the hot water at the upper part of the hot water storing tank 1 is pushed out and then the hot water is fed out of a hot water feeding plug.</p> |
