<P>PROBLEM TO BE SOLVED: To provide a hot-water storage type hot-water supplier capable of preventing energy waste or heating pump's degradation caused by an unnecessary continuation of heating switch's on-state. <P>SOLUTION: The hot-water storage type hot-water supplier has a hot water storage tank 1 for storing a liquid heat medium, a burner 5 for maintaining the heat medium within a prescribed temperature range by heating, the heating pump 13 for circulating the heat medium between the hot water storage tank 1 and an arbitrary number of heating terminal units 15, and a heating switch for starting the heating pump 13 operated by users. It is provided with an abnormal state discriminating means for judging whether or not the circulating state of the heat medium from the hot water storage tank 1 to a heating terminal unit 15 is abnormal regardless of the on-state of the heating switch based at least on the operating condition of the burner 5. <P>COPYRIGHT: (C)2004,JPO |
