PURPOSE: A method for controlling the heating of gas boiler is provided to prevent the temperature increase more than necessary and the excessive heat of heat exchanger and to save fuel cost by setting up the flux of the initial combustion gas low and increasing the flux of combustion gas in steps. CONSTITUTION: A device is composed of a control unit, a gas flux control unit, a set-up time lapse unit, an ignition unit and a temperature comparison unit. In an ignition step, a gas valve is opened, and gas is erupted through a burner installed inside a heating part. The erupted gas is ignited to heat a heat exchanger since a flame is generated by a transfer, and a signal is sent to a first gas flux control step. In the first gas flux control step, it is controlled with a low flux in order to increase the flux of combustion gas in steps, and the signal is sent to a set-up time lapse step. In the gas flux increase step, the gas flux burned in the burner is increased by one step, and a heating mode is driven. Further, in a set-up temperature arrival judgement step, it is judged that it reaches the temperature set up by a user via the set-up time lapse step. When not reaching the set up temperature, a process to increase the gas flux one step more is repeated via the gas flux increase step.
