<P>PROBLEM TO BE SOLVED: To provide a highly reliable hot water supply system capable of properly detecting a hot water storing amount of a hot water storing means. <P>SOLUTION: The hot supply water system has a first flow rate detecting means for detecting the flow rate of water passing through a water supplying flowing channel and the second flow rate detecting means for detecting the flow rate or water discharged from the hot water storing means during boiling up operation and detects the hot water storing amount in a hot water storing tank by integrating the detected flow rate by the second flow rate detecting means during the boiling up operation as a hot water increasing amount, and by integrating the detected flow rate by the first flow rate detecting means during supplying hot water as a hot water reducing amount. <P>COPYRIGHT: (C)2012,JPO&INPIT |
