PROBLEM TO BE SOLVED: To dispense with a gas-liquid separation device by altering a hot water supply outlet so as to eliminate air bubbles at a hot water outlet of a hot water storage tank because a conventional hot water storage tank requires the gas-liquid separation device separately arranged from the hot water storage tank in order to eliminate the gas bubbles from hot water. SOLUTION: The hot water storage tank L keeps a temperature of the hot water constant by circulating the hot water with a separately arranged heating device by using a cylindrical sealed vessel as the hot water storage tank L, and is provided with an exhaust and hot water delivery port X comprising an outer pipe 11, inner pipe 12, exhaust pipe 13 arranged on an upper end of the hot water storage tank L. The outer pipe 11 is fixed air-tightly around a hole bored on an upper end part of the vessel and opens upward. An opening is closed by a plate 15. The inner pipe 12 is fixed by passing through the plate 15, and a lower end is projected from a lower end of the outer pipe 11 to an inside of the vessel. The exhaust pipe 13 is fixed by passing through the plate 15, a lower end is adjacent to the plate 15, and an automatic air vent valve is provided on an upper end. COPYRIGHT: (C)2007,JPO&INPIT
