The present invention relates to a method for controlling switchover combustion according to a rise grade of a heating temperature. The present invention comprises a step of determining whether a heating operation switch is turned on in a control unit of a boiler; a step of starting the operation of an accumulated combustion timer operated during a predetermined total combustion time; a step of starting the operation of a first time including predetermined first time; a step of determining whether a heating water tapping temperature (Tout) rises over a predetermined heating load standard temperature (Tref) when the first time set by the first timer passes; and a step of clearing the first timer and turning back to the step of starting the operation of the first time again if the heating water tapping temperature (Tout) is under the predetermined heating load standard temperature (Tref) after the first time passes.
