<p><P>PROBLEM TO BE SOLVED: To provide a storage type hot water supply device capable of safely supplying hot water even if a hot-water supply flow sensor gets out of order. <P>SOLUTION: When the hot-water supply flow sensor is broken down and unable to detect start/stop of supplying hot water, the start of supplying hot water is detected by reduction in detected temperature by a hot-water supply thermistor by predetermined degrees of temperature during a predetermined time, and the stop of supplying hot water is detected by temperature rise by predetermined degrees of temperature during a predetermined time. Accordingly, the start/stop of supplying hot water can be securely detected, and the device can be used at ease without worrying about burns, etc., even when the hot-water supply flow sensor gets out of order. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
