One、Maintenance of radiators
1、Full immersion maintenance
After shutting down the heating system, whether it's a centralized heating system or a wall-mounted boiler independent heating system, regardless of whether it uses steel radiators, cast iron radiators, or copper-aluminum composite radiators, it is best to perform a full water maintenance. Full water maintenance can prevent oxygen from entering the radiators and heating pipes, reducing the dissolved oxygen in the water, and preventing oxygen corrosion, thereby extending the lifespan of the radiators.
2. Check for any leaks.
After shutting down the heating system, the temperature of the heating equipment will decrease due to the phenomenon of thermal expansion and contraction. This may cause water leakage at the joints and valves of the pipes. Therefore, we remind everyone to carefully check for water leakage at the joints after shutting down the heating system. If water leakage is detected, please contact professional personnel for on-site repair immediately.
3. Daily Cleaning
The gaps and surfaces of radiators often accumulate dust and grime. When cleaning, it is best to use soft cloths or brushes to avoid damaging the surface coating. After cleaning, radiators should not be stored in direct sunlight, as this can significantly accelerate the aging of the surface coating, especially if the surface coating is primarily plastic-sprayed or baked, which can greatly reduce their lifespan.
II. Maintenance of Underfloor Heating Systems
1、Regularly clean the underfloor heating pipes.
After shutting down the underfloor heating system, a comprehensive inspection of the equipment is required. The underfloor heating system utilizes a pipe circuit structure, with complex pipe shapes, long pipe lengths, and the formation of biological sludge and scale inside the pipes due to variations in water temperature. Over time, this can affect the heating temperature of the underfloor heating system and, in severe cases, lead to blockage.
The normal cleaning cycle for underfloor heating pipes should not exceed 2 heating seasons. After stopping heating, thoroughly clean the underfloor heating pipes to remove dirt, debris, and bacteria that may have formed within the pipes, preventing the buildup of deposits that could cause blockages. The cleaning and maintenance of underfloor heating pipes is a complex process, and it is recommended to contact professional personnel for on-site cleaning.
2. Regularly inspect the separators.
Under proper installation and reasonable system pressure, the lifespan of the separating valves is generally long. After shutting off the heating system, it is important to check for any cracks or other malfunctions in the separating valves. After experiencing harsh winters, it is important to prevent cracks in the separating valve components and water freezing and clogging the heating pipes, which can cause leaks.
III. Boiler Maintenance
After 2-3 years of use, it is necessary to clean and maintain the wall-hung boiler. Internal cleaning can effectively remove scale and reduce the load on major components such as the water pump and heat exchanger, reduce wear and tear on operating parts, and reduce the failure rate, resulting in smoother operation of the wall-hung boiler.
Cleaning the internal components of the wall-mounted furnace can ensure efficient and stable operation, effectively eliminating potential hazards. It can also improve the heat exchange efficiency of the wall-mounted furnace and reduce gas consumption.
