Currently, many families install gas wall-hung boilers in their bathrooms because they allow for personalized adjustment of bathroom temperature. However, for gas wall-hung boilers that we use frequently, do we all know how to maintain them? Let's learn about the maintenance methods for gas wall-hung boilers. As scale adhering to the inner wall of the heat exchanger continues to thicken, the diameter of the heat exchanger pipe will become smaller and smaller, and water flow will become less smooth, which not only increases the burden on the pump. It also reduces the heat exchange efficiency of the gas wall-hung boiler. The main symptoms are increased gas consumption, insufficient heating, reduced hot and cold domestic hot water, and less hot water. If the heat exchange components of the gas wall-hung boiler eventually remain in such a high-load state, the damage to the gas wall-hung boiler will be very serious, especially the plate heat exchanger, which is more harmful, so users should pay special attention to the choice of wall-hung boiler brand. Most of the heaters we use are made of cast iron. Sand mold residues and other impurities in the radiators cannot be completely removed during engineering installation; furthermore, the water in the heating system is always closed and circulated, and the heating part of the gas wall-hung boiler does not have a filter, allowing corrosion residues from the heater and pipes, as well as impurities from the water itself, to enter the heat exchanger. The heater then passes through the gas wall-hung boiler's circulation pump again. 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 pipe diameter thinner. Therefore, the pressure on the circulation pump further increases, and long-term operation will reduce or even jam the speed of the gas wall-hung boiler's circulation pump, seriously affecting its service life. For the heating system, because the heating elements accumulate a large amount of impurities during first 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. Since each water replacement introduces a large amount of alkali, the alkali content in fixed water is constant; therefore, the water in the heating system should not be changed frequently. After the heating season ends, you only need to clean and maintain the gas wall-hung boiler separately. The above is the maintenance content for gas wall-hung boilers, and we hope it helps you.
