After heating, how to maintain the radiator?

The weather is getting warmer, and the heating period that accompanies us in the whole winter is over. When the radiator at home is out of service, we need to carry out maintenance in time, which can not only increase the service life of the radiator, reduce the risk of water leakage, but also make the radiator operate faster and better in the next year. Let's see what we need to do next?

1. Appearance cleaning

After a winter of use, the surface of the radiator will inevitably adhere to some dust, oil stains, so to clean, it is recommended to use a clean cloth dipped in a little soap water or detergent, gently wipe can be clean as new. It is not allowed to use strong corrosive solution, nor to scratch with hard cleaner, which will damage the paint on the radiator, expose the metal tube inside, and make the radiator more prone to oxidation and corrosion.

2. Pipeline cleaning

As the heat source is cut off, the radiator of the user's home will gradually cool down. Due to the principle of thermal expansion and contraction, water dripping is easy to occur at the heating pipe fittings, especially at the movable joint of the heating. Therefore, within one or two days after the heating is stopped, it is necessary to pay attention to whether the condition of the heating in the home is in good condition. If there is water dripping or leakage, don't panic. If there is slight water dripping, you can use utensils to connect water and inject water Italy observation, most of the drips will be eliminated by themselves in a few days. If the drips become more and more serious, please contact the professional personnel for on-site maintenance. In order to prevent the sundries in the heating system from blocking the pipeline, there will be a filter or a filter screen inside. If the radiator has been used for many years, it should be cleaned in time to avoid the blockage of the pipeline caused by the accumulation of sundries, which will affect the heating in the next winter.

3. Exhaust the air

Open the vent valve of the radiator, remove the air in the radiator, and then close the vent valve, which can prevent the inner wall of the radiator from contacting with the air and increase oxidation corrosion.

4. Full water maintenance

The radiator needs full water maintenance. After heating, the water inlet valve and return valve should be closed, which can not only prevent the air from entering the radiator to accelerate the oxidation of the inner wall, but also prevent the leakage during the pressure test next year.

5. Do not change the heating facilities

Within one week after heating, it's better not to modify the heating pipeline, because most of the pipelines will have residual water, which will cause water leakage and unnecessary loss.
