Japanese Patent JP2977625
Kind Code:
B2
Abstract:
PURPOSE:To reduce noise of a pump and reduce consumed power by providing a bypass pipe connected to a supply pipe, a proportional valve for controlling the amount of supply gas, a tank, an electrical heater, and an automatic mixing valve where hot water is mixed with low temperature water to a predetermined target set temperature correspondingly effluent hot water temperature and supplying the effluent hot water to a supply plug side. CONSTITUTION:In a hot water effluent state, there is outputted target set temperature hot water correspondingly hot water temperature existent in a supply pipe 12 located between an automatic mixing valve 21 and a hot water supply plug 16. Then, high temperature water flowing from a tank 17 into the automatic mixing valve 21 is mixed with cold water flowing in from a water supply pipe 25 through a bypass line 20 into the target set temperature and is supplied to the hot water supply plug 16 side for delivery of hot water. On the contrary, since the temperature in a circulation line 10 in the neighbourhood thereof where the water supply pipe 25 is connected is lowered owing to the supplied water from the water supply pipe 25, a gas burner 30 is actuated and hence the water supplied to a heat exchanger 13 is heated so as to get a predetermined high supply temperature and is supplied to the tank 17.
