The radiator is idle until the next heating season. Therefore, it is necessary to clean and protect the radiator before heating. It is also essential to properly maintain the radiator.
Steel radiator maintenance
The maintenance radiator mentioned here is mainly for the Tianjin steel radiator. The corrosion of steel by oxygen contained in central heating systems is a major problem that steel radiators have been difficult to solve. It requires that the oxygen content of water is not large 0.1mg/m3, pH = 10-12, although it is required that the hot water used for the radiator must be subjected to oxygen removal treatment, but most of them are still difficult to implement; and for some reason there is a large area of ​​concentrated heating The system cannot seal the entire system, resulting in the inability to isolate it from oxygen. In addition, the water supply is not maintained after the heating is stopped. As a result, the oxygen content in the system exceeds the standard, and oxidative corrosion cannot be avoided, especially in the wet state. more serious. Therefore, steel radiators are generally maintained in full water. That is, after the heating is stopped, the heating return valve is closed first, the air release valve is opened, air is released, and finally the water valve is closed.
Steel and aluminum composite radiator maintenance
The steel-aluminium radiators, which are lighter than steel radiators, have the advantages of good pressure resistance of the steel radiators, resistance to alkali and corrosion, and quick heat transfer and low energy consumption of the aluminum radiators. However, as with steel radiators, full-water maintenance is also required.
Copper and aluminum composite radiator maintenance
Because the copper-aluminum composite radiator has no restrictions on the PH value of the system water quality and the residential heating system, and the copper-aluminum composite radiator has the advantages of good corrosion resistance, strong anti-corrosion performance and good heat dissipation effect, and is more suitable for northern water quality and complicated heating. The system also does not need full water maintenance.
Aluminum radiator maintenance
The high-quality aluminum profiles together with advanced argon gas protection welding technology and special internal anti-corrosion coating technology have created the advantages of light weight, corrosion resistance, fast heat conduction and low energy consumption. Therefore, aluminum radiators do not require full water maintenance, do not generate rust debris, and do not block waterways.
Heater maintenance after warming
Emilia Radiator reminds you that what you need to do after warming up is to make the radiators in your home full of water. After you stop warming, users should not let water out of the radiators, or they can let go of the water, but pay attention. Dry the water droplets in the radiator to ensure the inside is dry, otherwise it will rust and corrode like iron.
Radiator has unique charm as heating equipment in modern life. Cast iron radiators have gradually withdrawn from the market stage. Steel radiators, copper-aluminum composite radiators and other new radiators are superior to cast iron radiators both in terms of materials and production processes, and they become the most popular radiators on the market.
