<p><P>PROBLEM TO BE SOLVED: To reduce the change of hot water supply temperature from a shower or a faucet to stably supply hot water to the shower or the faucet when the bath hot water is performed during supplying the hot water from the shower or the faucet. <P>SOLUTION: A control portion learns a hot water supply flow rate to a bathtub on the basis of past performance of hot water supply to the bathtub 14, and controls an opening of a hot water supply hot water/water mixing device 10 on the basis of the learned hot water supply flow rate to the bathtub 14, when the hot water supply to the bathtub 14 is started during supplying hot water from a hot water supply terminal 8 (9). The flow rate in supplying hot water to the bathtub is learned on the basis of use performance in bath hot water supply reflecting conditions of each house, and the hot water/water mixing of the hot water supply hot water/water mixing device 10 is controlled on the basis of the learned value when the bath hot water supply is started during supplying hot water from the shower or the faucet and the like, even when installation conditions of a bath and a kitchen, and a condition of water line pressure are various in every house. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
