How to maintain and service a gas wall-hung boiler

Many families now install gas wall-hung boilers in their bathrooms for personalized temperature control. However, for gas wall-hung boilers that we frequently use, do we all know how to maintain them? Let's learn about the maintenance methods of gas wall-hung boilers. As the scaling attached to the inner wall of the heat exchanger continues to thicken, the diameter of the heat exchanger tube will become smaller and smaller, and the water flow will become less smooth. This not only increases the burden on the pump but also reduces the heat exchange efficiency of the gas wall-hung boiler. The main manifestations are increased gas consumption, insufficient heating, reduced hot and cold sanitary hot water, etc. If the heat exchange components of the gas wall-hung boiler are ultimately kept in such a high load state, the damage to the gas wall-hung boiler will be very serious, especially the damage to the plate heat exchanger is greater, and users should pay special attention to the choice of wall-hung boiler brand. Most of the heaters we use are made of cast iron. The sand mold residue and other impurities in the radiator cannot be completely removed during the engineering installation process; in addition, the water in the heating system is always turned off and circulated, and the heating part of the gas wall-hung boiler has no filter, causing the corrosion residue and impurities in the water itself in the heater and pipes to enter the heat, and the heater is circulated again through the circulation pump of the gas wall-hung boiler. These impurities will continue to decompose at high temperatures, some of which will scale and adhere to the inner wall of the gas wall-hung boiler, making its tube diameter thinner. Therefore, the pressure of the circulation pump is further increased, and long-term operation will reduce or even jam the speed of the circulation pump of the gas wall-hung boiler, seriously affecting its service life. For the heating system, since a large amount of impurities will accumulate in the heating pieces during the first use, it is recommended to drain the dirty water after one year of use, refill it with new water, and replace it after a few years. Because each water change will introduce a large amount of alkali, the alkali content in the fixed water is certain; therefore, the water in the heating system should not be changed frequently. After the heating season, you only need to clean and maintain the gas wall-hung boiler separately. The above is the maintenance content of the gas wall-hung boiler, hoping to be helpful to you.
