<P>PROBLEM TO BE SOLVED: To obtain a storage water heater capable of easily boiling hot water with temperature and quantity corresponding to a user need even when the number of temperature sensors for detecting the temperature of hot water within a hot water storage tank is reduced. <P>SOLUTION: In the storage water heater for supplying hot water stored in the hot water storage tank from the hot water storage tank to a predetermined hot water supply destination, a control device includes a boiling control part for making a heat source machine boil hot water when detection temperature by a predetermined temperature sensor (third boiling temperature sensor) out of the temperature sensors detecting the temperature of the hot water within the hot water storage tank is a first condition value or lower, calculating necessary time required for boiling hot water with preset temperature and quantity when the detection temperature by the predetermined temperature sensor is equal to or more than a second condition value, and making the heat source machine finish the boiling of the hot water after the necessary time passes after the detection temperature by the predetermined temperature sensor is equal to or more than the second condition value. <P>COPYRIGHT: (C)2010,JPO&INPIT |
