Gas bath boilers, also known as gas bathhouse boilers or gas swimming pool boilers, are a type of hot water boiler specifically designed to use combustible gases as fuel to automatically supply hot water for meeting people's bathing needs in an environmentally friendly manner. Combustible gases mainly include natural gas, city gas, liquefied petroleum gas, biogas, and other flammable gases. With the implementation of the national "West-East Gas Transmission" project and environmental protection requirements, gas bath boilers have gradually become the preferred choice for swimming pools, bathhouses, bathing centers, and other facilities.

       Gas bath boilers are equipped with controllers and burners to heat the heat medium water to 40-45°C. By using a hot water circulation pump to force the circulation of water between the boiler and the insulated water tank, the temperature is kept consistent to achieve the purpose of bathing. Gas bath boilers are widely used in government agencies, enterprises, factories, hospitals, schools, hotels, and other institutions.

       Based on structure, they can be classified into vertical gas bath boilers and horizontal gas bath boilers;

       Based on construction, they can be classified into atmospheric gas bath boilers and pressurized gas bath boilers;

       Based on fuel, they can be classified into natural gas bath boilers, city gas bath boilers, biogas bath boilers, liquefied petroleum gas bath boilers, etc.
