Regularly clean the heat exchange tubes of the wall mounted boiler

The heat exchange tubes of wall mounted boilers should be regularly cleaned and maintained. This not only maintains the heat exchange efficiency and improves the service life of the furnace, but also saves energy, reduces consumption, and promotes the healthy and sustainable development of the wall mounted boiler industry.

Gas wall mounted boilers have the characteristics of independent self-control, safety and environmental protection, and energy-saving and multi-purpose. It is widely used in household heating and water supply, especially in floor radiant heating, and its development speed is also relatively fast. The potential and space for the future are still on the rise.

However, after using the wall mounted boiler for several years, due to water quality and other reasons, scaling is more severe inside the copper ring tube of the inner pot or on the plate exchange device, causing poor water flow, significantly reducing heat transfer efficiency, and severe blockage, resulting in the wall mounted boiler being unusable. According to the different water quality in various regions of our country, the above situation usually occurs after about 3 years of use for wall mounted boilers, and some may even occur for a shorter period of time. In order to maintain the heat exchange efficiency and extend the service life of wall mounted boilers, it is necessary to regularly clean and maintain the heat exchange tubes and plates inside the wall mounted boiler.

The water quality and treatment in our country are not good, and scaling of heat exchange tubes is inevitable. Moreover, after high-temperature water quality analysis, hard scale is formed, which must be cleaned with chemicals. Moreover, our operators and users lack sufficient mental preparation and are not familiar enough with the consequences of scaling. They are faced with technology products that cost thousands or even tens of thousands of yuan but cannot be used due to the heat exchange tube structure, and are helpless. Once replaced, it increases a lot of investment. Some operators also try to extend the service life of the furnace through cleaning in the after-sales service process, but due to the lack of professional cleaning knowledge and specialized cleaning equipment, most people's efforts are not very effective. There are several common aspects:

One reason is that the analysis and testing of scale quality and quantity are insufficient, and the cleaning agents used are incorrect, which does not work on the scale inside the pipe and cannot be cleaned.

Secondly, insufficient consideration was given to the factors that cleaning agents can cause corrosion to heat exchange tubes, resulting in severe corrosion and leakage of heat exchange tubes after cleaning.

The third issue is pipe blockage caused during the cleaning process. To effectively clean the heat exchange tubes of wall mounted boilers, it is necessary to have a certain level of cleaning knowledge and specialized cleaning equipment; Then different cleaning agents should be prepared according to different scales. The water quality and composition of scaling vary in different regions of our country; Finally, effective cleaning technology training should be provided to cleaning operators. Professional cleaning equipment and specialized training institutions for wall mounted boiler cleaning have emerged and will soon be promoted nationwide.
