<P>PROBLEM TO BE SOLVED: To provide a hot water supply device for filling a bath with hot water in a short time while securing a sufficient supply amount of hot water. <P>SOLUTION: A pressure sensor is provided in a hot water supply passage for measuring water pressure in the hot water supply passage. The pressure in the hot water supply passage is changed depending on the opening of a faucet. When the pressure is high, hot water is rushed by opening the faucet, and when the pressure is low, a desired amount of hot water is supplied only by largely opening the faucet. The state that the sufficient supply amount of hot water is not obtained when largely opening the faucet, because of the lower pressure in the hot water supply passage, is determined as the state that the supply amount of hot water is insufficient, and the amount of hot water supplied to a bath filling passage is limited to secure the supply amount of hot water. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
