How to maintain radiators
As winter approaches, the frequency of use of radiators gradually increases. To ensure efficient operation and long service life of your radiator, regular maintenance is essential. This article will introduce the maintenance methods of radiators in detail and provide structured data for reference.
1. The importance of radiator maintenance
After long-term use of the radiator, dust, scale and other impurities are easy to accumulate inside, resulting in a decrease in heat dissipation efficiency, and may even cause problems such as water leakage. Regular maintenance can not only improve heating efficiency, but also save energy and reduce maintenance costs.
2. Radiator maintenance steps
| steps | Operation content | Things to note |
|---|---|---|
| 1. Close the valve | Before maintenance, first close the water inlet and outlet valves of the radiator to ensure that the system is in a stopped state. | Avoid hot water splashing during operation. |
| 2. Clean the surface | Wipe the surface of the radiator with a soft cloth to remove dust and stains. | Avoid using corrosive cleaning agents. |
| 3. Check for leaks | Carefully check the radiator and pipe joints for signs of leakage. | If water leakage is found, it should be repaired promptly. |
| 4. Exhaust | Open the exhaust valve to exhaust the internal air and ensure smooth water flow. | The valve needs to be closed after exhausting. |
| 5. Flush the interior | Use professional cleaning agents to rinse the inside of the radiator to remove scale. | It is recommended to do this every 2-3 years. |
3. Maintenance points for radiators made of different materials
| Material | Maintenance points | FAQ |
|---|---|---|
| cast iron radiator | Regularly check the sealing of the interface to prevent rust. | It is easy to accumulate dirt and needs frequent cleaning. |
| Steel radiator | Avoid leaving it empty for a long time to prevent internal oxidation. | The water quality requirements are higher. |
| Copper-aluminum composite radiator | Pay attention to moisture and avoid corrosion. | The price is higher, but the life is long. |
4. Common misunderstandings about radiator maintenance
1.Neglecting internal cleaning: Many people only clean the surface and neglect to clean the internal scale, resulting in a decrease in heat dissipation efficiency.
2.Frequent opening and closing of valves: Frequent operation of the valve will accelerate the aging of the seals and increase the risk of water leakage.
3.Use inappropriate cleaning agents: Strong acid and alkali cleaners will corrode the surface of the radiator and affect its service life.
5. Seasonal suggestions for radiator maintenance
| season | Maintenance suggestions |
|---|---|
| winter | Exhaust air regularly to ensure heating effect; check for water leaks. |
| summer | Close the valve and drain the internal water; clean the surface dust. |
6. Professional maintenance service recommendations
If it is difficult to maintain it yourself, it is recommended to contact a professional heating company to provide services. The following are common maintenance items and cost references:
| Services | Cost range (yuan) |
|---|---|
| Internal cleaning | 150-300 |
| Leak repair | 200-500 |
| Comprehensive testing | 100-200 |
Summary
The maintenance of radiators is the key to ensuring the heating effect in winter. Through regular cleaning, checking for leaks and internal flushing, the service life and efficiency of the radiator can be effectively improved. Radiators made of different materials require targeted maintenance measures to avoid common misunderstandings. If conditions permit, it is recommended to perform professional maintenance every 2-3 years to ensure the stable operation of the heating system.
