Abstract: To solve a problem that there is the possibility that occurrence of fan clogging might increase the amount of gas jetting out from a burner due to reduction in inner pressure of a combustion casing and thus cause incomplete combustion in a water heater that includes a fan supplying combustion air into the combustion casing with a burner and a hot water supply heat exchanger built therein and a proportional valve interposed in a gas supply passage and that controls fan rotational frequency on the basis of a combustion characteristic line indicating a correlation between a proportional valve electric current value predetermined to perform normal combustion of the burner and the fan rotational frequency.SOLUTION: When an exhaust clogging rate is a predetermined value or greater and a proportional valve electric current value Ip is equal to or greater than a predetermined electric current value YIp close to an upper limit value, actual combustion amount Qj calculated from heating amount in a heat exchanger and a design combustion amount Qs calculated from the proportional valve electric current value are compared with each other. When Qj is larger than Qs by a predetermined rate or greater, a combustion characteristic line used for controlling fan rotational frequency is switched to correction combustion characteristic line L1-L5 in which a change rate of the fan rotational frequency relative to the proportional valve electric current value is set larger than a reference combustion characteristic line L.SELECTED DRAWING: Figure 2
