Abstract
A method for gas supply pressure control is disclosed. Gas is supplied to a gas burner at a gas supply pressure which is higher than an ignition pressure, and after the ignition of the gas burner, the gas supply pressure increases during a predetermined time until fluid to be heated reaches a target temperature. The increase of the gas supply pressure is performed gradually according to a predetermined number of pressure levels set between the ignition pressure and maximum gas supply pressure of the gas boiler. If the fluid reaches the target temperature, the gas is supplied according to a corresponding to the target pressure temperature. Since the time that the gas is supplied at the maximum gas supply pressure is reduced during the time of initial operation of the gas boiler and during the operation of the gas boiler, the noise resulting from combustion is reduced.
