<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply device allowing grasping of an amount of used supplied hot water of each hot water supply path without using an expensive flow rate detecting means even in a hot water supply device using a system directly using high temperature hot water in a hot water storage tank. <P>SOLUTION: The hot water supply device is provided with a high temperature hot water supply path 24 for supplying only the high temperature hot water stored in the hot water storage tank 1, a first flow rate detecting means 62 provided in a water supply path 12 for detecting a flow rate of water flowing in the water supply path 12, a second flow rate detecting means 72 provided in a mixed hot water path 17 for detecting a flow rate of mixed hot water flowing in the mixed hot water path 17, and a flow rate calculating and tapping determining means 200 for calculating a flow rate of the high temperature hot water flowing in the high temperature hot water path 24 and determining tapping of the high temperature hot water on the basis of the flow rate detected by the first flow rate detecting means 62 and the flow rate detected by the second flow rate detecting means 72. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
