The invention discloses a gas water heater self-adaption wind pressure resisting control method. The method is characterized in that when it is set in advance through a main controller that no external wind pressure exists, each fan current corresponds to a fan rotating speed, and each fan rotating speed corresponds to a gas proportional valve current value; when external wind pressure exists, a constant-current control mode is adopted, and fan current corresponding to the same load stays the same; in this way, when external wind pressure increases, constant current is maintained by increasing the voltage of a fan; the input power of the fan becomes larger with the increase of the voltage of the fan, the rotating speed of the fan is increased, and meanwhile, the current of a gas proportional valve is controlled to increase according to the optimal wind-air ratio. The constant-current control mode is adopted, and waste gas backflow or down draft is effectively avoided; meanwhile, the wind-air ratio is automatically adjusted according to the change of the rotating speed of the fan, and it is guaranteed that smoke and efficiency are in the optimal state.
