LIJU has developed its own WCB water-cooled premixed ultra-low NOx combustion technology, combining it with vacuum boiler manufacturing methods to create the ultra-low NOx vacuum hot water Boiler. This product different with other boiler for its innovative design . The water-cooled system ensures the combustion process is efficient, and controlled, which resulting in a high thermal efficiency.
One of the important features of the boiler is its ultra-low NOx emissions, which are kept below 15ppm, making it an ideal choice for projects focused on reducing environmental impact. It makes the boiler suitable for using in green buildings , where performance and sustainability are very important.
The boiler is designed to provide efficient heating while meeting strict emissions standards. It is the perfect solution for residential, commercial, and industrial buildings that require a consistent hot water supply .
Thanks to the advanced technology, our Gas Hot Water Boiler not only delivers excellent heating performance but also plays a important role in energy conservation and eco-friendly initiatives. In a new building or as part of a retrofit, it all offers a clean, cost-effective, and environmentally responsible solution .
If you are looking for a reliable and green heating solution, Our Gas Hot Water Boiler is the perfect choice for your next project.
■ Ultra-low NOx emission: <15ppm (down to 9ppm)
■ Condensing efficiency up to 103%
■ Output: 350KW - 14MW
■ Compact packaged design


1. How do I maintain my hot water boiler?
Periodic inspection and cleaning of the heat exchanger to ensure stable hot water supply;Checking boiler pressure and keeping it within the normal range;Replacing aging or damaged components, such as safety valves and pumps;Annual inspections by a professional to ensure optimal performance.
2.Can a hot water boiler heat multiple locations?
Yes, It can heat multiple areas through distribution systems such as hot water circulation pipes and distribution valves.
3.How long does it take to install a hot water boiler?
The installation time depends on the size and complexity of the boiler.
