<P>PROBLEM TO BE SOLVED: To provide a hot water supply system capable of deriving a piping capacity from a mixer to a heating section in a bath test operation of supplying water into a bathtub. <P>SOLUTION: This hot water supply system 10 executes a bath test operation program. The bath test operation program includes (1) a process for supplying mixed water flowing out from the mixer 24 to the bathtub 72 through a hot water supply pathway 70, (2) a process for changing a mixing ratio in the mixer 24 during (1), (3) a process for specifying time difference between a time when a water temperature detected by a mixing thermistor 27a reaches a prescribed temperature and a time when a water temperature detected by a hot water supply thermistor 57 reaches the prescribed temperature, (4) a process for specifying a flow rate of the mixed water, and (5) a process for deriving the piping capacity from the neighborhood of an outlet of the mixer 24 to the neighborhood of a burner heat exchanger 53 on the basis of the time difference and the flow rate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
