Everyone is aware that radiator corrosion typically occurs after the heating system is turned off. If proper maintenance isn't performed following the shutdown, it can significantly shorten the lifespan of radiators—especially steel and aluminum ones. To address this issue, Yuan You Radiator Factory has introduced several effective maintenance techniques to reduce oxidation and corrosion in radiators, particularly in Shanxi. Here are the main methods:
1. Before the radiator system stops running, open the exhaust valve to release air from the radiator. Once all the air is expelled, close the exhaust valve and the water outlet valve, then fill the system completely with water for full-water maintenance. This step is crucial. On one hand, homeowners need to be proactive about radiator maintenance. On the other hand, reliable valves should be installed at both inlet and outlet ports during installation. If this isn’t possible, air entering the system will create a corrosion-prone area where air and water meet. Some might argue that steel radiators have an anti-corrosion coating and are resistant to damage. However, this assumption is overly simplistic and not entirely accurate.
2. Even the best aluminum radiators should be maintained with full water. Aluminum is sensitive to alkaline and electrochemical corrosion, and most boiler water is alkaline. When the system is shut down, this type of corrosion may accelerate, especially as ions become more active. In central heating systems, I recommend avoiding aluminum radiators if possible. Pay close attention to the connection between the aluminum radiator and the pipes. If white powder appears at the joint, it's likely alumina formed by electrochemical reactions. At this point, it’s best to wipe the joint with non-volatile grease to slow down further corrosion. If water seeps into the gap, the radiator could be nearing the end of its life.
3. During the winter, dust often accumulates on the surface of radiators. Use a clean cloth to wipe it off. If the dirt is stubborn, you can use a little soapy water, then wipe it clean with a dry cloth. Avoid using strong corrosive chemicals or sharp objects that could scratch the surface.
4. For convection radiators with heavy dust buildup, use a soft brush or cloth to clean them. If the cover needs to be removed, handle it carefully to avoid damaging the surface or internal components.
5. If a radiator is temporarily removed, do not leave it in direct sunlight. Most radiators have a painted or baked finish, and prolonged exposure to sunlight can cause the coating to age quickly, reducing the overall lifespan of the unit. For cast iron radiators, sun exposure can cause the gasket to shrink, leading to potential leaks within the system.
