The floor heating was stopped two days ago, and after the first winter test, everything is normal. Now that the floor heating is not in use, how should I maintain it? Do you want to release the water? Should the pressure be relieved or maintained?
The above problem is how to strengthen maintenance and management during the period of the underfloor heating system is out of operation, and it is also an important link to ensure the 50-year operating life of the underfloor heating system. Therefore, the reader raised this question, how to strengthen the maintenance after the floor heating stops running, and what should be done to improve the service life of the floor heating system, it is worth learning.
At present, there are a lot of discussion about the regulation and regulation in the heating system operation and management period, and there is less discussion about the maintenance of the heating system during the shutdown period. In particular, how to maintain the system after the floor heating is out of operation is more worthy of discussion. Therefore, the author has consulted the relevant information during the shutdown and maintenance period of domestic and foreign ground heating systems for readers' reference.
After the ground heating system stops running, the hot water heating system pipe network is generally maintained with water. The method is to release the water in the pipe network, flush the pipe network (including heating coils), and then refill the pipe network with chemically treated water and burn the boiler to heat the water in the system to 60°C , The temperature is maintained for 1~1.5h, and then the air separated from the water is discharged out of the system through the opened system exhaust valve. After exhausting, close all the valves in the system, turn off the furnace, let the water cool down gradually, and keep the water in the pipe network of the system until the next heating period begins.
After the heating period is terminated, the system must be carefully maintained and managed daily. Of all the external damage and destruction of the system, the ones that occurred during the shutdown period account for a large proportion, not to mention that all parts of the system are often damaged by oxygen corrosion during this period. Only a floor heating system that is equally meticulously maintained and properly managed during operation and shutdown can ensure long-term reliable operation.
