Problems solved by technology

However, the combustion effect of gas water heaters will be limited by the gas supply conditions of users' homes. Some users' homes may have problems with gas water heaters not working properly due to insufficient gas supply pressure of the overall pipe network or insufficient gas supply during peak gas consumption, affecting hot water production. The speed and user bathing experience
[0003] At present, the maximum gas pressure in my country is about 3000Pa, but the gas pressure is seriously insufficient during the peak gas consumption, which will inevitably cause the following problems: First, the gas pressure may be lower than 1000Pa during the peak gas consumption, resulting in the failure of the gas water heater to start normally; The working principle of gas water heaters, low air pressure directly affects the speed of hot water outlet; third, the poor stability of air pressure affects the stability of outlet water temperature, which will be directly felt by users during use, greatly affecting user experience
[0004] At present, there are no related gas booster water heater products in the market. When the pressure is low, the ratio of gas to air is only adjusted by controlling the proportional valve, and the pressure stability of the gas behind the proportional valve is improved by increasing the opening of the proportional valve. The effect of this method is very limited when the pressure is below 1000Pa
