特徴とするガス湯沸器。 A diaphragm device having a diaphragm installed in a water supply passage communicating with a heat exchanger heated by a gas burner and displaced according to the amount of water flowing to the heat exchanger; In a gas water heater equipped with a gas valve that increases or decreases the amount of gas supplied, the water supply passage is configured to reduce the amount of displacement of the diaphragm with respect to the amount of water flowing in accordance with a rise in the temperature of the water supply, regardless of the temperature of the water supply. First, there is a water supply temperature compensation valve that allows the heat exchanger to always provide hot water at a substantially constant high temperature, and a restriction that restricts the amount of water flowing to the heat exchanger from exceeding a maximum flow rate corresponding to the maximum capacity of the gas burner. A constant flow valve is provided, and the constant flow valve is fitted into a fitting hole formed on the inner surface along the water supply passage so as to be slidable in the axial direction, and has an inward flange portion with an opening in the center. a moving cylinder, a tapered member that is provided so as to be movable in the axial direction concentrically with the sliding cylinder, and a portion of which is inserted into the opening to form a variable throttle portion between the sliding cylinder and the water supply passage; one of the sliding tube and the tapered member is positioned by being biased toward the upstream side of the water supply passage by a spring, and when moved downstream, the sliding tube and the tapered member are positioned in the passage of the variable throttle section. The other of the sliding tube and the tapered member is connected to the thermally responsive member and moves in the axial direction as the temperature of the thermally responsive member increases to increase the passage area of the variable throttle portion. A gas water heater characterized by being configured as follows.
