Document Type and Number:
Japanese Patent JP2500123
Kind Code:
B2
Abstract:
PURPOSE:To an effective output hot water temperature responsive to a using purpose by instructing, releasing a fluctuation mode by an operation of a fluctuation instruction switch, releasing the mode by sensing stop of water supply by water supply sensing means, and removing a complicated operation of releasing the fluctuation mode. CONSTITUTION:A supply water flow rate sensor 31 is provided in a feed water tube 13 to a main heat exchanger 11, and an output supply hot water temperature thermistor 33 is provided in an output hot water tube 15. The signals from the sensors are input to a controller which varies the quantity of heat of a main burner 2 and varies a temperature of hot water as a time goes. The controller instructs and releases modes in response to the operation of a fluctuation switch, decides a target quantity of heat of the burner 2 according to information of the sensor 31, etc., and automatically releases the fluctuation mode if the sensed flow rate of the sensor 31 becomes an operation stopping flow rate or less. Accordingly, a complicated operation of releasing the fluctuation mode is eliminated, and an output hot water temperature responsive to a using purpose can be obtained without fluctuation at the time of using a hot water supply.
