PURPOSE:To provide the supply of hot water at a desired temperature irrespective of a faucet opening and in spite of change in the hot water temperature by regulating the outflow amount in the excessive opening of the faucet with a heat responsive element at the hot water supply side of proportional control system gas hot water supply equipment to correct the water supply amount in water temperature change with a heat responsive element at the water supply side. CONSTITUTION:When heated supply water is sent to a faucet, a heat responsive element 7 in a heat sensing chamber 4 senses the heat of hot water outflow at a set temperature to project a drive piece 7a by a certain amount so that the distance L of a flow regulator 25 is varied to maintain the outflow at a certain value and the maximum hot water outflow amount is maintained constant even if water supply pressure is varied. Thus, though the opening of hot water supply faucet is enlarged, the outflow hot water amount is not increased more than the maximum value. Also, when supply water temperature is lowered, a heat responsive element 33 senses it to reduce the projection amount of the drive piece so that a movable cylinder 18 is moved left by a spring 35. Accordingly, an O-ring 29 of the flow regulator 25 is also moved left to throttle the water supply amount. Thus, when the maximum capacity curve of the hot water supply equipment is moved as shown by the chain line, the water supply amount is automatically corrected to regulate the hot water outflow amount. |
