Extraordinary! Heating is coming to an end, do you know all these precautions?

2025-04-28

After the heating is stopped, the temperature of the heating equipment decreases. Affected by thermal expansion and contraction, it may cause water leakage at individual pipe interfaces and valves. Therefore, it is necessary to regularly check whether the floor heating system has leakage, especially at the connection pipes and valves. If slight dripping is found, a towel can be used to absorb water. If the leakage is serious, you can contact a professional for door-to-door maintenance.


Under normal circumstances, the cleaning cycle of the floor heating system is 1 to 2 years. It is recommended to ask professionals to clean the heating pipes to ensure that the pipes are unobstructed and the heat dissipation effect is normal.


After the heating is stopped, the heating supply and return valves are closed. At the same time, the air in the pipe is discharged through the exhaust valve to avoid air blocking the flow of hot water and reducing thermal efficiency. The softened water in the pipeline can effectively isolate the corrosion of the air to the radiator and the pipeline.


after the heating is over, the water in the system will cause thermal expansion and contraction of the parts in the process of alternating between hot and cold. Check whether there is leakage or loosening at the connection of the radiator and the pipe, which needs to be tightened or repaired.


Make sure that the internal exhaust of the radiator system is complete to prevent the air from hindering the flow of hot water. It is important to carry out an exhaust operation after the heating season, which can effectively prevent oxygen corrosion and rust. This step can effectively prevent rust for steel radiators.


make sure that the water pressure in the radiator system is within the normal range, not too high or too low. In addition, check the water quality regularly to avoid excessive impurities and oxygen in the water to reduce corrosion.


the task of "their" heating system this year has been completed. "They" silently protect our cold in the heating season. We should also protect "their" health in the non-heating season. We will see
