<p><P>PROBLEM TO BE SOLVED: To optionally set the shape of a hot water storage tank and the pressure of hot water delivery in a hot water supply system, and to facilitate an extension of a hot water storage tank. <P>SOLUTION: This hot water supply system includes: an atmospheric open type medium temperature water tank 1 storing water supplied; a heat pump 2 for heating water; an atmospheric open type high temperature water tank 3 storing heated hot water; and a hot water supply pump 17 for delivering hot water of the high temperature water tank 3. The high temperature water tank 3 can be serially or in parallel connected to one or more atmospheric open type extension tanks 13 at the lower parts by a communicating pipe 12. Hot water is stored by each hot water temperature in the high temperature water tank 3 and the medium temperature water tank 1, and the high temperature water tank 3 and the medium temperature water tank 1 are of atmospheric open type, so that the tank can be constructed in an optional shape, and the extension of tanks can be facilitated. Further, hot water delivery can be performed by the hot water pump regardless of pressure of city water, so that the pressure of hot water delivery can be set at an optional value. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
