As shown in fig. 1-4, the intake passage 300 is provided with a proportional valve 310, an outlet of the proportional valve 310 is located at an upstream of the branch duct 500 and the main ventilation duct 400, and the proportional valve 310 can adjust the size of the intake opening under the control of the main controller, so as to adjust the intake speed and achieve the purpose of adjusting the flame size of the burner assembly 200 and the ever-burning flame chamber 220. The proportional valve 310 may also be completely closed to block the gas in the inlet channel 300 from entering the main air duct 400 and the branch duct 500, so that the flame in the burner assembly 200 and the long-fire combustion chamber 220 is extinguished, and the heating and heat preservation of the water are stopped. The proportional valve 310 can simultaneously control the flame size of the burner assembly 200 and the flame size of the ever-burning fire burner 600, so as to better adapt to the change of the temperature of the water heater using environment, avoid the condition that the temperature of hot water is too low in winter or too high in summer, and be beneficial to controlling the water temperature and keeping the water temperature in a more comfortable state.

Separate switches may be provided on the main ventilation duct 400 and the branch duct 500, respectively, to control the main ventilation duct 400 and the branch duct 500, respectively. Thus, when the burner assembly 200 is used for combustion, the main air duct 400 can be opened and the branch duct 500 can be closed; when the long open flame burner 600 is used for combustion, the opening and closing of the branch duct 500 are opened and the opening and closing of the main air duct 400 are closed.
