Abstract (en)
[origin: EP2853839A1] A hot water supply system 1 configured to sequentially store high-temperature water produced in a heat source machine 2 while forming temperature stratification, and maintain a set temperature, the system including: a bypass circuit 26 that is provided between a high-temperature water pipe 15 so as to bypass warm water spouted from the heat source machine 2 to the low-temperature water system by a switch valve 25 when the warm water has a low temperature at initiation of a heat retaining operation for maintaining the warm water stored at a given temperature; and a valve control section 27 that switches to the hot water storage tank 11 the warm water having a low temperature bypassed to the bypass circuit 26 by using an R value, which is a mixture characteristic value of the temperature-stratified hot water storage tank based on the temperature of the warm water, as an index.
