1. How to deal with the radiator after the heating is stopped
1. The radiator is best maintained with full water
Wall hanging The independent heating system of the type household boiler, whether it is a steel radiator, a cast iron radiator or a copper-aluminum composite radiator, it is best to keep it full of water. Full water can isolate oxygen, reduce the oxygen content in the water, prevent oxygen corrosion, and prolong the service life of the radiator.
2. Replace the old radiator in time
For problems such as not hot in the heating season, water seepage in the welds or seams, serious surface deformation, etc. The radiator used should be checked and maintained by a professional radiator installer. If you need to replace the new radiator as soon as possible, the radiator that has exceeded its service life is neither energy-saving nor environmentally friendly. It is recommended to replace it in time during the shutdown period.
3. Check whether the pipeline is leaking
After the heating is stopped, the temperature of the heating equipment will decrease. Due to thermal expansion and cold contraction, it may cause the joints and valves of the pipeline water leakage. Therefore, it is recommended to carefully check the seams for leaks after stopping the heating. If there is a slight leak, you can tie a towel and it will suck the water away without harming the floor and walls in the short term. If the water leak is serious, please ask the HVAC company to check and repair it as soon as possible.
4. Do not dismantle the heating facilities at will after the heating is stopped
It is best not to modify the heating pipes within a week after the heating ends, because most There will be excess water in the pipes, and any carelessness can lead to leaks, causing unnecessary trouble for yourself and your neighbors.
5. No one at home needs to close the main valve for a long time
Closing the central heating valve is the most effective way to prevent the leakage of central heating. If no one is home for a long time, the central heating valve must be closed to prevent water leakage in the central heating system.
Second, how to maintain the radiator during the non-heating period
During the heating off period, the radiator is put on hold, but there are still some things that need to be handled by the user, such as Maintenance and replacement of radiators, diversion of heating pipes when renovating houses. Do you know how to solve these problems?
1. Do you need to release the water in the central heating system after the heating stops?
Some users think that the water in the heating should be released after the heating stops, so as to Prevent rust on the inner wall of the radiator. In fact, having water in the heating system prevents rusting. This is because large amounts of chemicals are added to the heated water to prevent corrosion of the radiators and pipes. At the same time, the full water state also effectively isolates the contact between the air and the inner wall, reduces the probability of oxidation and corrosion, and prolongs the service life of the radiator and pipes.
2. Maintenance of radiator during non-heating period
First of all, it should be maintained with full water to prevent the radiator from being oxidized and corroded. Secondly, pay attention to cleaning the surface of the radiator, you can wipe it clean with a clean rag. For stubborn stains, use functional soapy water to wipe, do not use corrosive cleaners, and do not scratch with sharp objects to prevent damage to the radiator.
For the heating pipe, the filter screen of the filter must also be cleaned in time, so that in some users’ homes, the heating effect of the radiator is not ideal, and when the heating stops, they want to modify the system or replace the radiator. I recommend that users should wait a while or ask a professional to replace the residual water in the pipes when the shutdown begins, as leaks can easily occur during renovations. The radiator should be replaced with the same model as much as possible, and it is best to buy branded products in the mall.
