Under what circumstances is it most appropriate to clean and maintain wall mounted boilers?

With the development of the economy, more and more Chinese users are starting to use wall mounted boilers as independent heating equipment, experiencing the comfort and flexibility brought by this method. But after long-term use, the combustion of high-temperature flames, dust, vibration, water quality, and changes in water quality and temperament of your gas wall mounted boiler may affect its operating conditions, and its operational economy will decrease. According to European experience, wall mounted boilers that are maintained have a 6% increase in economic performance compared to those that are not maintained. After maintenance, your wall mounted boiler will greatly reduce the risk of malfunction and extend its service life. In addition, regular maintenance can also reduce the maintenance costs of gas wall mounted boilers. The warranty period for Hampton wall mounted boilers is 2 years, while the designed service life of wall mounted boilers is 15 years. Complex external factors can affect the operating conditions of wall mounted boilers. Regular maintenance can not only eliminate problems in their early stages, but also reduce the annoyance they may cause you once they occur.

Under what circumstances is it necessary to clean and maintain the wall mounted boiler?

1. Your wall mounted boiler has been continuously used for more than two heating seasons.

2. I feel that the gas usage of the wall mounted boiler has increased compared to before.

3. The heating time of wall mounted boilers increases, sanitary hot water is hot and cold, and the output of hot water per unit time decreases.

4. The operation sound of the wall mounted boiler increases, and there may be occasional abnormal noises

Maintenance knowledge of wall mounted boilers;

1. The scaling principle and hazards of wall mounted boilers: The core issues of wall mounted boilers are the efficiency and service life of heat exchange, and the biggest factor affecting these two aspects is the scale problem.

Especially when we use domestic hot water, due to the need to constantly add new water and the fact that the water quality in most areas is relatively hard, the scaling rate of the heat exchanger is greatly increased. As the scale attached to the inner wall of the heat exchanger continues to thicken, the diameter of the heat exchanger will become thinner and the water flow will become less smooth. This not only increases the burden on the water pump and heat exchanger, but also greatly reduces the heat transfer efficiency of the wall mounted boiler, mainly manifested as increased gas consumption, insufficient heating, intermittent heating of sanitary hot water, and reduced hot water volume. If the heat exchange components of the wall mounted boiler continue to operate in such a high load state, the damage to the wall mounted boiler will be very severe.

2. The impact of impurities and scale in radiators on boilers: Wall mounted boilers are responsible for the circulation of water in the heating system. Due to the presence of impurities and acidity in water, it can cause certain corrosion to radiators and pipelines. Most of the radiators we use are made of cast iron material, and the sand mold residue and other impurities inside the radiators cannot be completely washed away during engineering installation; In addition, the water in the heating system is always in a closed cycle, and the heating part of the boiler does not have a filter screen. Therefore, the rust residue and impurities in the radiator and pipes, as well as the water itself, will enter the heat exchanger again through the circulating water pump of the wall mounted boiler. These impurities continue to decompose at high temperatures, and some of them become scale and adhere to the inner wall of the heat exchanger, making its diameter thinner. As a result, the pressure of the circulating water pump will further increase, and long-term operation will cause the circulating water pump speed of the wall mounted boiler to decrease or even get stuck, seriously affecting its service life.

3. The water inside the radiator should not be replaced frequently: For the heating system, due to the large amount of impurities in the radiator during initial use, it is recommended to drain the dirty water after one year of use, refill with new water, and replace it after a few years. Because every time the water is changed, a large amount of water alkali is introduced, and the fixed alkali content in the water is constant; Therefore, warm

The water in the gas system should not be replaced frequently. After a heating season, cleaning and maintenance of the wall mounted boiler only need to be done separately.

4. What are the benefits of regularly cleaning and maintaining wall mounted boilers?

(1) It can improve the efficiency of heat exchange in wall mounted boilers and reduce gas consumption. Through experimental comparison, two wall mounted boilers that have been operated under the same conditions show that the wall mounted boiler that has been cleaned and maintained has a significantly faster heating speed of about 25% compared to the wall mounted boiler that has not been cleaned and maintained. This means that the wall mounted boiler can save about 25% of gas on the original basis after cleaning. If calculated based on a gas consumption of about 1000 yuan/month per 100 square meters of house, you will save about 800-1000 yuan on using wall mounted boilers for one year (including heating season)!

(2) Extending the service life of wall mounted boilers can effectively reduce the load on major components such as water pumps and heat exchangers through internal cleaning and descaling, thereby making the boiler operate more smoothly and extending its service life. If the boiler is cleaned and maintained every one to two years, it can extend the service life of the equipment by 3-5 years.

(3) To increase the safety of wall mounted boiler operation, through on-site cleaning and professional comprehensive testing and debugging of wall mounted boiler operation, problems that exist during operation can be timely and effectively discovered and eliminated to ensure safe operation of wall mounted boilers.
