<p><P>PROBLEM TO BE SOLVED: To provide a hot-water storage type water heating system capable of supplying hot water of respectively set temperature from a plurality of hot-water supplying terminals and capable of effectively using middle-temperature water inside a hot-water storage tank. <P>SOLUTION: This hot-water storage tank type water heating system is provided with a middle-temperature hot-water supplying pipe 29 for letting the middle-temperature hot-water inside the hot-water storage tank 2 flow, a middle-temperature water mixing valve 30 for mixing the high-temperature water from a hot-water supplying pipe 8 with the middle-temperature water from the middle-temperature hot water supplying pipe 29 to any predetermined temperature, a first mixing valve 37 for mixing the hot water mixed by the middle-temperature water mixing valve 30 with the low-temperature water from a first bypass pipe 38 to a first supplying hot-water set temperature to supply it from a first hot-temperature supplying terminal, a second mixing valve 41 for mixing the hot-water mixed by the middle-temperature water mixing valve 30 with the low-temperature water from a second bypass pipe 43 to a second supplying hot-water set temperature to supply it from a second hot-water supplying terminal. In the case of supplying hot-water from one hot-water supplying terminal, any predetermined temperature to be set by the middle-temperature water mixing valve 30 is a value higher by a certain temperature than the set temperature of the hot-water to be supplied from this one hot-water supplying terminal, and in the case of supplying hot-water from both the hot-water supplying terminals at the same time, it is set at a value higher by a certain temperature than the higher temperature of both the hot-water. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
