Abstract

PURPOSE: To enable a water boiler to correspond to wide use of hot water by allowing the switching of the faculty of a heat exchanger through heating with a plurality of burners and detecting the magnitude of the thermal output at controlling com- bustion by stages with an arithmetic controller.
CONSTITUTION: The passages 12W14 leading to a plurality of burners 4W6 are brached, and in said branched passages 13W14, electromagnetic valves 16 and 17 are installed respectively which are ON-OFF-controlled by an arithmetic controller 15 incorporated with amplifying circuits. When the knob of an instruction device 21 is manually operated to set a proper temperature, and a hot water feeding cock 26 is opened, a water pressure corresponding gas valve 9 opens to feed fuel gas. At this time, the difference between the established temperature and the water temperature detected by a thermistor 18 and the water amount detected by a water amount detector 20 are applied to a controller 15, and calucation is performed, and electromagnetic valves 16 and 17 are ON-OFF-controlled by stages. The temperature of hot water supplied through heating in an heat exchanger 1 is detected by a thermistor 19, and a linear control valve 11 is adjusted to control the gas feeding amount proportionally.
