<P>PROBLEM TO BE SOLVED: To improve convenience of adding water and provide energy saving effects by securing necessary temperature for the adding water in a hot water storage type hot ware supply system. <P>SOLUTION: This hot water storage type hot ware supply system is so constituted that a that pump 22 heats water in a lower part of a hot water storage tank 5 and high-temperature hot water is stored from the upper part of the hot water storage tank 5. The setting temperature of a hot water temperature setting means 28 is set high based on a signal of a delivery hot water detecting means 28 detecting the hot water delivery from the hot water storage tank 5, so that, when the hot water supply load is low and the stored hot water temperature is set low, the high-temperature hot water necessary for the adding water is secured in the upper part of the hot water storage tank by additional burning to improve the convenience in adding the water. The burning temperature is set according to the hot water supply load so as to reduce the heat radiation loss from the hot water storage tank 5 and provide the energy saving effects. <P>COPYRIGHT: (C)2003,JPO |
