1. The design, manufacture, supervision and inspection of domestic boilers are carried out in strict accordance with the "Safety Supervision Regulations of Hot Water Boilers" to ensure the long-term safe and stable operation of boilers.

2. The hot water boiler is designed for normal pressure, which is suitable for the domestic water demand of any unit, factory, construction site, school, hotel, etc.

3. Chinese multi-level menu, so that boiler monitoring is simple, organized, intelligent, using the current high-resolution color or black and white touch screen. It can dynamically display the running state of the burner, water pump, etc. And the real-time changing state of the flame.

4. Large water volume design, the furnace body is not sensitive to load fluctuations, and the load fluctuation range is still suitable for users.

5. With overpressure, water shortage alarm, ultra-low protection and other functions. When the power supply voltage exceeds the normal range or the water level is lower than the safe water level of the boiler, it will automatically cut off the boiler power supply and alarm.

6. The main body is a boiler shell type full wet reflux smoke cylinder structure, the flame burns under micro-positive pressure in the large combustion chamber, and the emission of harmful substances is less. The boiler can obtain good thermal performance, qualified flue gas emission index and wide range of burner adaptation when running under various loads.

7. The front and rear smoke boxes are made of special insulation materials, which have high temperature resistance, low thermal conductivity, rapid cooling resistance and good heat resistance. The characteristics of vacuum boilers greatly extend the service life of the smoke boxes. The lower part of the smoke box of the vacuum hot water boiler is provided with a condensate discharge port to reduce the corrosion of the condensed water to the pressurized parts.
