Abstract: PURPOSE: A controlling method of hot water flux of a gas boiler is provided to provide hot water in the desired temperature by controlling a flux regulation valve. CONSTITUTION: A flux flowing into a direct water pipe is detected. The temperature of the hot water flowing in a hot water pipe and the set up temperature by a user are detected. The thermal capacity is measured by measuring the amount of gas flowing in a gas pipe. A signal is transmitted to the step of comparing the use amount of hot water to the supply amount of hot water when the output is maximum. When the output is not maximum, the maximum state of the output(the thermal capacity) to another step of comparing the use amount of hot water to the supply amount of hot water is confirmed. If the use amount is the same as the supply amount, a signal is transmitted to a flux detecting step. When the output is minimum and the use amount is lower than the supply amount, a signal is transmitted to the flux control step. If the use amount is the same as the supply amount, a signal is transmitted to the flux detecting step. The flux is reduced by the signal transmitted at the comparing steps. And the flux is increased by the signal transmitted at the comparing steps.
