Answer: The specific details of wall-hung boiler maintenance are as follows:

First, under what circumstances does the wall-hung boiler need to be cleaned and maintained.

1. If your wall-hung boiler has been used continuously for more than two heating seasons.

2. The running sound of the wall-hung boiler becomes louder, and there will be abnormal sound.

3. There is something wrong with the heating of the wall-hung boiler, the heating speed is slow, the hot water is cold when taking a bath, the water outlet speed is slow, and the water output is smaller.

The use of gas is obviously increased than before.

Second, the wall-hung boiler maintenance instructions

1. When the gas wall-hung boiler is not used for a long time, if the power supply is turned off, make sure to turn on the boiler power switch once a month to prevent the water pump from rusting.

2. It is best to cover the equipment with dust-proof things to reduce the damage of dust to the equipment. If there is dust, it needs to be wiped with a clean and soft cloth.

3. When it is not used temporarily in winter, the power supply cannot be cut off, so the anti-freezing function will fail.

4, gas wall-hung boiler flue should be cleaned regularly, regularly check whether it is blocked by foreign bodies, resulting in poor smoke exhaust. If it is blocked, it will report the failure of the air pressure switch, making it unable to open.

5. For seasonal inspection, it is recommended to ask professionals to maintain it once a year.

6. Check the burner and main heat exchanger and clean them if necessary. Wall-hung boilers can be cleaned at the end of the heating season. The main heat exchanger and burner cannot be cleaned with chemicals or steel brushes.

7. In places where it is easy to freeze, if the wall-hung boiler is not applicable, the water in the system should be discharged; If antifreeze is added to the system, there is no need to empty the system.

8. It is suggested to use special scale inhibitor (calcium magnesium compound is more than 450mg/L) in hard water area.

9. There is a lot of dust in the air, which will flow with the air on the surface of the wall-hung boiler, which will reduce the heat conversion efficiency in the long run, thus affecting its quality. Clean the surface dust with a clean towel every week to avoid corrosion of its materials or parts and reduce the use time.

What is the effect of regular maintenance of wall-hung boilers?

1. can improve the heat exchange efficiency of Anrui wall-hung boiler and reduce gas consumption. Compared with two wall-hung boilers operating under the same conditions, the heating speed of the wall-hung boiler after cleaning and maintenance is obviously about 25% faster than that of the wall-hung boiler without cleaning and maintenance, which means that the wall-hung boiler after cleaning can save about 25% gas on the original basis. If the gas consumption per 100 square meter of the house is around 600 yuan/month, you can save about 800- 1000 yuan in one year (including the heating season).

2. Extend the service life of the wall-hung boiler, effectively reduce the load of main components such as water pump and heat exchanger through internal cleaning and descaling, and make the boiler run more smoothly and prolong the service life. If the boiler is cleaned and maintained once every two years, the service life of the equipment can be extended by 3-5 years.

3. Increase the safety of the wall-hung boiler. Through the door-to-door cleaning and professional comprehensive inspection and debugging of the running wall-hung boiler, the problems existing in the operation of the wall-hung boiler can be found and eliminated in time and effectively to ensure the safe operation of the wall-hung boiler.
