PURPOSE: A control method for a boiler is provided to reduce energy and to maintain indoor temperature and floor temperature by controlling the deviation of the indoor temperature within ±0.5°C and the deviation of returning water temperature within ±1°C. CONSTITUTION: A control method comprises: a step of turning on of a boiler power(S11); a step of setting returning water temperature corresponding to indoor temperature(Tws) when the boiler power is turned on(S12); a step of setting variable indoor temperature(Trv) during sleeping time corresponding to the indoor temperature(S13); a step of setting variable returning water temperature(Twv) during sleeping time corresponding to the variable indoor temperature during sleeping time(S14); a step of setting the setting indoor temperature(Trs) with a temperature setting switch(23)(S15); a step of detecting the indoor temperature(Tr) with an indoor temperature sensor(24)(S16); a step of detecting returning water temperature(Tw) with a returning water sensor(12)(S17); a step of checking current time with a timer(S18); and a step of determining current time which is checked in the checking step(S18) whether it is sleeping time or not(S19).
