Claims

[Scope of utility model registration request]

(1) A water heater that heats a heat exchanger with a burner is equipped with a temperature sensor that detects the temperature of water entering the heat exchanger and the temperature of hot water exiting the heat exchanger, as well as a gas control valve that controls the amount of gas flowing into the burner, and a gas control valve that controls the amount of gas flowing into the burner. A water control valve is installed to control the amount of water.
A hot water supply device comprising a water control means that allows the water control valve to have a maximum allowable flow rate for a set hot water supply temperature.

(2) The above-mentioned water control means is the necessary increase in temperature y determined by the ratio of the control output value that controls the gas control valve and its maximum output value, or the inlet water temperature, outlet water temperature, and set temperature after the water temperature has stabilized. A water heater as set forth in Figure 1-18, Item 1 of the Utility Model Registration Claim, characterized in that it has a calculation unit that calculates the ratio to temperature, and controls a water control valve in accordance with the calculation value. .
