<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply system capable of supplying hot water until hot water storage amount becomes low, and boiling up hot water until hot water storage tanks are filled with hot water, in the hot water supply system having the plurality of hot water storage tanks in parallel with each other. <P>SOLUTION: This hot water supply system 1 comprises a heat source machine 2 for boiling up the supplied water, the plurality of hot water storage tanks 3 for storing the boiled-up hot water, a switch valve 4 connecting upper portions of the hot water storage tank 3, a hot water supply pipe 53 connected with the switch valve 4, a temperature sensor 6 for detecting the hot water storage amount, and a control portion 7 for controlling switching motion of the switch valve 4. The control portion 7 calculates hot water storage amounts of the hot water storage tanks 3, and increase and decrease thereof on the basis of a hot water temperature detected by the temperature sensor 6, and switches the switch valve 4 according to results of the calculations. Thus hot water supply and hot water storage can be combined, the hot water can be supplied until the hot water storage amount of the hot water storage tanks 3 becomes low, and the hot water can be boiled up until the hot water storage tanks 3 are filled with the hot water. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
