Abstract

PURPOSE:To perform proper room heating, using as one pleases and improve comfortable feeling by setting a specific ratio of combustion quantity in the time of weak combustion to strong combustion and providing stages of heating capacity switches for controlling temperature in combustion variable width. CONSTITUTION:In an operation part 10 heating capacity switches 17a-17g set to control heating in the combustion variable width in which the combustion quantity in the time of weak combustion corresponding to strong combustion is 1/2 are arranged. When an operation switch 16 is turned on, current is supplied into an evaporating heater 19; when temperature is more than prescribed temperature, the current is supplied into an igniter 20, a pump 7, a burner blower 21, and a convection blower 5 respectively and combustion is started. A microcomputer control circuit 22 controls the function part of the pump 7 and the like on the basis of contents set in the operation part 10, and the temperature of heating room is controlled. In other words in the case where set temperature is higher than detecting temperature of a room temperature thermistor 9, the combustion is performed in the strong combustion quantity selected by the heating capacity switches 17a-17h and in the case where the set temperature is lower than the detecting temperature of the room temperature, the combustion is performed in the weak combustion quantity selected.
