摘要： PURPOSE:To improve a hot water feeding characteristic and a responding characteristic when a set temperature is varied by a method wherein a heating calorie of a heat source for use in heating and a heat exchanger is controlled and a flow rate in a bypassing water passage is adjusted to control an amount of mixed water. CONSTITUTION:When a set temperature TMS is inputted and a hot water feeding is started, an already set water amount distribution ratio (r) is applied to calculate a target temperature THS at a target temperature calculation part 14. A water temperature Tc of water flowing into a main water passage 2 and a water volume Q1 flowing in a heat exchanger 1 are detected and then a gas proportional valve 8 is FF controlled in such a way as hot water of the target temperature THS is fed out of the heat exchanger 1 under a control of gas amount FF control part 15. If it is confirmed that a water amount Q1 passing through the heat exchanger 1 is more than an assured flow rate Qm of MOQ, and that a bypassing servo valve 4 is not fully closed, an outlet temperature TH of the heat exchanger 1 and a mixing temperature TM are detected. When the detected temperature TH and TM are near the target temperature THS and the set temperature TMS (for example, 1.5 to 1.0 deg.C), the servo valve 4 is stopped and a spare hot water feeding mode is applied to FB control the gas proportional valve 8. In the even that the value is not present within the aforesaid range, the gas proportional valve 8 and the servo valve 4 are FB controlled to supply hot water of set temperature TMS.

摘要： PURPOSE:To make the best use of a hot water supply capacity by eliminating such a hazardous chance that hot water at higher temperature than a preset temperature be discharged even when an attempt is made to open a general hot water supply faucet during the supply of hot water from a hot water supply channel designed for bath and moreover supplying the maximum amount of mixed hot water at the preset temperature from a general hot water supply channel. CONSTITUTION:When each flow rate detected by a water incoming sensor 8, a bypass water sensor 11, and a bath flow rate sensor 17 exceeds a specified flow rate, a second flow rate control valve 13 is controlled based on a detected flow rate Q1 by the water coming sensor 8 where a target flow rate Q2 is set so that it may exceed the newest detection flow rate Q1 by alpha. Moreover, a first flow rate control valve 12 is adapted to control that mixed hot water temperature TM shall conform to general hot water supply preset temperature TMS. The mixed hot water temperature TM is specified as the preset temperature TMS. In the mean time, when the supply amount of hot water is increased and the flow rate control valve 12 or 13 reaches the maximum valve opening position, the flow rate control valve 13 is adapted to indicate Q5=Q1 while the flow rate is arranged to indicate TM=TMS.
