PURPOSE:To prevent the sandwich phenomena of cold water upon restarting the flowing of water by a method wherein a forced combustion of a given time is effected after a predetermined time from a time point when a flow detector has detected the flow of water in case a combustion demand, hased on the output signal of a water temperature sensor, is not leting obtained. CONSTITUTION:In the control device for hot-water supplier, in which the ignition and extinguishing of burners 3, 4 are effected to keep hot-water supplying temperature in constant utilizing the output of the flow detector 21 for detecting the flow of water for the water pipeline of a heat exchanger and the output of the water temperature sensor 5 provided on the way of the water pipeline, the device is equipped with a circuit 10 commanding the forced combustion of a given time after a predetermined time from the time point when the flow detector 21 had detected the flow of water in case the combustion demanding signal, based on the output signal of the water temperature sensor 5, has not been obtained. Thus, the sandwich phenomena of cold water, which is caused upon restarting the flowing of water, may be prevented. |
