<p><P>PROBLEM TO BE SOLVED: To provide a hot-water supply device capable of easily detecting a failure of a flow rate detection means. <P>SOLUTION: A control device 200 determines that at least either of both flow rate counters 62 and 72 is in a failure state when a flow rate detected by the flow rate counter 62 is smaller than that of the flow rate counter 72, and displays information of the failure state on a display part 110 of an operation panel 100. Thereby, it is annunciated to a user or the like that at least either of the flow rate counters 62 and 72 is in the failure state and repair can be facilitated. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
