Claims

[Scope of utility model registration request]

In a hot water circulation path formed by connecting in series a water supply port, an inlet water temperature thermistor, a branch part, a water flow rate sensor, a heat exchanger, an outlet water temperature thermistor, a three-way control valve, an outlet water temperature thermistor, and a hot water supply port, The main body containing the three-way control valve is integrally provided with a mounting part for attaching each thermistor and sensor, and a bypass passage connecting the branch part and the three-way control valve, so that the three-way control valve can supply cold water and hot water. A hot water temperature control device for a gas water heater, which has a function of mixing and controlling the temperature of hot water discharged, and a throttle function of controlling the amount of hot water discharged.
