Why choose
Vacuum Hot Water Boiler?

The vacuum hot water boiler operates on the principle that water has a lower boiling point under low pressure. By rapidly heating the thermal medium water enclosed in the boiler, high-temperature steam is produced. This steam condenses on the heat exchange tube, heating the cold water inside the tube to effectively supply hot water. The device is designed to operate under negative pressure, avoiding hazards such as expansion, explosion and rupture. It has features such as high efficiency and energy saving, and safety and reliability with thermal efficiency up to 96%.

The vacuum hot water boiler can provide solutions for multiple needs such as heating, domestic hot water, and swimming pool heating at the same time. The highly efficient heat exchanger adopts stainless steel design to prevent scaling and corrosion, and prolong service life. The boiler and heat exchanger are designed as a whole, saving space and reducing floor area, and adopting a fully automatic control system to achieve high automation without the need for special personnel.

Widely used in civil areas such as hotels, residences, office buildings, bath centers, schools and shopping malls, it provides stable and reliable hot water supply. The vacuum hot water boiler which uses imported burners not only has high combustion efficiency, but also controls noise and exhaust emissions at extremely low levels, reflecting the environmental friendliness of the equipment.
