Abstract: PURPOSE: A method for controlling operation of retaining heat in gas boiler is provided to prevent freezing of a gas boiler, to inhibit the generation of water drops owing to low temperature, and to prevent the drain phenomenon, i.e., corrosion of piping owing to the generation of water drops by maintaining a heating temperature in room at a constant level when a user returns home, so that a productivity of a gas boiler is improved, efficiency thereof is maximized, and an economic loss is minimized. CONSTITUTION: A method for controlling operation of retaining heat in gas boiler comprises the following steps: a step for performing a heating operation after determining whether a heating operation or a hot water operation is required(S1-S5); a step for performing a normal combustion for heating by a temperature difference(.delta.T), if a state that the user's set temperature(Tset) is lower than a minimum temperature(X°C) is not maintained for a set time period(Ysec) during the heating operation(S6-S7); a step for performing a pause mode in which gas combustion in the gas boiler is extinguished, if a state that a thermistor(TH1) or a thermistor(TH2) is higher than a heating operation performing temperature(L°C) is maintained for a set time period(Msec) when a state that the set temperature(Tset) is lower than the minimum temperature(X°C) is maintained for a set time period(Ysec)(S8-S9); a step for recognizing again a temperature of adding a desired temperature(A°C) to the set temperature(Tset) as a set temperature(Tset1), performing the heating for retaining heat, and displaying the rapid heating, if the thermistor(TH1) or the thermistor(TH2) is lower than a heating operation performing temperature(L°C) or if it is maintained within the set time period(Msec)(S10-S11); and a step for determining again whether a state that the thermistor(TH1) or the thermistor(TH2) is higher than the heating operation performing temperature(L°C) is maintained for the set time period(Msec) or not based on a temperature difference(.delta.T) between the thermistor(TH1) and the thermistor(TH2)(S12, S8).
