摘要： PROBLEM TO BE SOLVED: To control a hot-water-running temperature to a setting temperature accurately by correcting a map for supplying hot water while a hot-water-supply system is operated independently so that the map becomes larger and smaller at sides where the calorific values of a heat generation part are large and small, respectively, when the map for supplying water is corrected to a side where the amount of the heat of hot-water-supply is reduced while the hot-water-supply system and a reheating system are operated simultaneously. SOLUTION: When a hot-water-running temperature is to be controlled by a control unit 50, the hot-water-running temperature is adjusted by the opening of an electromagnetic proportion valve 4B while a hot-water-supply system is operated independently. In this case, the amount of heat being required by hot-water-supply is calculated based on a setting temperature, the quantity of water supply, a water-supply temperature, a hot-water-running temperature, and the quantity of hot-water supply. After that, the opening of the electromagnetic proportion control valve 4B for obtaining the amount of the heat being required by hot-water- supply is obtained from a map for supplying hot water. Also, when the hot-water-supply system and a reheating system are operated simultaneously, one portion of the amount of heat by a burner 1 is taken by reheating and the map for supplying hot water is corrected to a side where the amount of the heat of the hot-water-supply is reduced. In this case, the map is corrected so that it becomes smaller and larger at sides where the opening of the electromagnetic proportion valve 4B is small and large, respectively.

摘要： PROBLEM TO BE SOLVED: To enable an accurate discrimination whether a gas supplying/discharging pipe fixing system is a double-pipe system or two-pipe system by a method wherein a fixing system for a gas supplying pipe and a gas discharging pipe is discriminated as a double-pipe system when a temperature of the supplied gas is higher than a predetermined temperature and in turn it is discriminated as a two-pipe system when a temperature of the supplied gas is lower than a predetermined temperature. SOLUTION: A temperature sensing means such as a thermistor or the like is fixed to an appropriate portion of a gas supplying passage 50. The temperature sensing means measures a temperature of the supplied gas. Then, a combustion device 1 compares a measured gas supplying temperature with a predetermined discriminating temperature. The discrimination temperature is set to be higher than a temperature of the surrounding atmosphere and further set to be lower than a temperature of the supplies gas in the case of applying double-pipe system during combustion. Then, if the measured temperature of the supplied gas is higher than the discrimination temperature, the combustion device 1 discriminates that the gas supplying or gas discharging pipe fixing system is of a double-pipe system, and in turn if the temperature is lower than the discrimination temperature, it discriminates that the system is of a two-pipe system. The combustion device 1 performs a combustion control which is different in the case of the double-pipe system and of the two-pipe system, and the most- suitable combustion state is maintained.

摘要： PROBLEM TO BE SOLVED: To assuredly prevent the supply of high temperature hot water during the the resupply of hot water and stabilize the temperature of resupplied hot water. SOLUTION: A bypass valve opening/closing temperature setting part 39 sets the valve opening temperature and the valve closing temperature (valve opening temperature > valve closing temperature) of a bypass valve 10 higher than an observed outlet side hot water temperature during the stop of combustion of a hot water supply heat exchanger detected by an outlet side hot water temperature sensor 14 during the stop of the hot water supply and combustion of a hot water supply burner. The time of flow of hot water from the hot water supply heat exchanger which reaches a part at which a bypass passage for a bypass valve 10 is joined to a hot water supply passage from a part in which the outlet side hot water temperature sensor 14 is provided is detected by a flow time detecting part 40 based on the detected flow rate of a flow rate detecting sensor 12 or the like. A bypass valve drive means 38 opens the bypass valve 10 when the flow time of hot water passes after the detected temperature of the outlet side hot water temperature sensor 14 during the resupply of hot water reaches temperature not lower than the valve opening temperature of the bypass valve 10. The drive means 38 closes the bypass valve 10 when the flow time of hot water passes after the temperature detected by the outlet side hot temperature sensor 14 reaches temperature not higher than the valve closing temperature of the bypass valve 10.

摘要： PROBLEM TO BE SOLVED: To make it possible to supply hot water of less temperature- fluctuations when starting the resupply of hot water even when the function of a bath is driven during the standing time for the resupply of hot water. SOLUTION: A stand-by time measuring means 2 measures the stand-by time for the resupply of hot water while a bath operation time measuring means 3 measures bath operation time during stand-by time of the resupply of hot water. When the bath function is operated and a combustion fan is driven during the stand-by time of the resupply of hot water, a lost heating value estimation detection unit 5 detects a lost heat volume retained by a hot water supply heat exchanger based on the fan rotary volume information of the combustion fan during the bath operating time. A gas quantity correction unit 6 for starting operation corrects the starting gas quantity to a hot water supply burner, responding to this retained lost heat volume, thus stabilizing the resupplied hot water temperature when starting the resupply of hot water.

摘要： PROBLEM TO BE SOLVED: To prevent a hot water temperature from varying due to the switching of the combustion surface of a hot water supplying burner at the time of a resumption of a hot water supplying by a method wherein when a required combustion heating value of the hot water supplying burner becomes larger than a combustion stage unchanged part, the throttle quantity of a hot water quantity control valve is regulated to be smaller so that the required combustion heating value may become a heating value at an igniting position which is one stage higher. SOLUTION: A required heating value calculating part 26 obtains required combustion heating values at the time of an ignition of a hot water supplying burner and at the time of a combustion of the hot water supplying burner by a coming-in water temperature, a hot water supplying set temperature, and a coming-in water quantity to a hot water supplying heat-exchanger. For combustion control lines, on combustion control lines of respective stages other than a combustion control line for the highest stage, a combustion stage unchanged area is provided as a combustion stage unchanged part. Then, a water quantity control valve throttle quantity regulating means 30 applies a valve throttle quantity regulating signal to regulate a set throttle quantity of the water quantity control valve smaller so that when a required combustion heating value at the time of an ignition of the hot water supplying burner becomes larger than the combustion stage unchanged part, it may become the required combustion heating value of an ignition position on the one stage higher combustion control line.
