<p><P>PROBLEM TO BE SOLVED: To provide a hot water storage type water heater capable of using up the stored water of high temperature. <P>SOLUTION: This hot water storage type water heater comprises a hot water storage tank 1 for storing warm water heated by a heating means 2, a water supply pipe 3 for supplying the feed-water to the hot water storage tank 1, a hot water supply pipe 4 communicated with an upper portion of the hot water storage tank 1 for supplying the water of high temperature, and a hot water supply temperature sensor 13 for detecting a temperature of warm water supplied from the hot water supply pipe 4, and hot water supply is stopped by closing a cutoff valve 15 disposed in the water supply pipe 3, when the hot water supply temperature sensor 13 detects the hot water/water temperature lower than a hot water supply set temperature for more than a specific time, thus the stored warm water can be used up at ease, and economic performance and usability can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
