With the end of the winter heating season in the north, many families are faced with a common question: Do they need to turn off the heating valve after the heating is turned off? Recently, an experienced heating maintenance master reminded everyone that closing the heating valve after the heating is turned off has multiple benefits, including reducing rust stains, reducing the deposit of impurities, and preventing water leakage.
First of all, closing the heating valve can effectively reduce the occurrence of rust stains. During heating, water in the heating system is constantly circulating, which can lead to rust stains on the inside of pipes and valves. After the heating is stopped, if the valve is not closed in time, the water in the system will remain in the pipes and remain still for a long time, which will exacerbate the formation of rust stains. When the valve is closed, the water in the system flows out, reducing the time it takes for the water to come into contact with the metal pipes, thus reducing the occurrence of rust stains.
Secondly, closing the heating valve also helps to reduce the accumulation of deposited impurities. During heating, impurities such as sediment and rust in the water may enter the heating system with the flow of water and deposit at pipes and valves. If the valve is not closed after the heating is stopped, these impurities may continue to deposit inside the pipes, affecting the normal operation of the system. When the valve is closed, the water in the system is discharged, taking away most of the deposited impurities, helping to keep the system clean.
Finally, closing the heating valve can prevent water leakage from occurring. After the heating is over, pipes and valves may have small cracks or loosens due to thermal expansion, cold contraction, aging, etc. If the valve is not closed in time, water in the system may seep through these cracks or loosens, causing a water leak. When the valve is closed, no water can flow out even if there are small cracks or loosening, thus avoiding the loss of water leakage.
As for how to properly close the heating valve, the heating maintenance master also gave advice. He reminds everyone that before closing the valve, it is important to ensure that the water in the system has been completely drained to avoid water being trapped in the pipes due to improper operation. At the same time, before the next heating starts, the status of the valve should be checked in advance to ensure that it can be opened normally to ensure the normal operation of the heating system.
In conclusion, it is a recommended measure to turn off the heating valve after the heating has been stopped. Not only does it reduce rust and sedimentary impurities, but it also prevents water leakage, helping to extend the life of your heating system and ensure the safety and comfort of your home. Therefore, it is recommended that the majority of users close the heating valve in time after the heating is stopped, and check and maintain it before the next heating.
