The invention provides a control method of a water heater, the water heater and a readable storage medium. The control method of the water heater comprises the following steps that a pressure detection device is controlled to obtain the gas outlet pressure value of a gas outlet of a gas proportional valve; and the opening degree of the gas proportional valve is adjusted according to the gas outletpressure value, and the rotating speed of a fan is also adjusted according to the gas outlet pressure value. The water heater can automatically adjust the opening degree of the gas proportional valveand the rotating speed of the fan, self-adjustment is achieved, and therefore a user does not need to adjust various parameters of the water heater, and the use convenience of the user to the water heater is improved. When the gas outlet pressure value is abnormal, it shows that the opening degree of the gas proportional valve and the rotating speed of the fan need to be adjusted, the output heatof the water heater can me
