Maintenance skills of wall-hung boiler;

1. Regularly check whether there is leakage at the joint of gas valve, pressure reducing valve and pipeline, and tighten or replace it if found. It is also necessary to purge the gas path regularly to remove dust and dirt. The inside of the boiler needs to be cleaned once a year to ensure that the flue is unobstructed. For wall-hung boilers that are not used for a long time, the gas in the boiler must be drained and washed clean before ignition.

2. The heating system is generally closed, and the internal water will not interact with the external water. After a period of use, water no longer contains air, but it is the best.

3. Full water maintenance can isolate oxygen, reduce oxygen content in water, prevent oxygen corrosion and prolong the service life of wall-hung boiler. Completely cut off gas, water and electricity to achieve no consumption. If you turn off the power supply, you'd better unplug it, because there are many thunderstorms in summer, and lightning strike may damage the wall-hung boiler.

4. After the heating is stopped, the temperature of the wall-hung boiler facilities decreases, which may lead to the phenomenon of thermal expansion and cold contraction, resulting in water leakage at the pipe joints and valves. Therefore, it is necessary to carefully check whether there is water leakage at the interface, so as not to endanger the floor and walls.
