How to turn on the heating
As winter approaches, heating system maintenance becomes a focus for many households. Heating pressure test is an important step to ensure the normal operation of the heating system, especially before the heating season, potential problems can be discovered and repaired in time. This article will introduce in detail the steps, precautions and related data of heating pressure to help you complete this operation smoothly.
1. Basic concepts of heating suppression
Heating compression refers to injecting high-pressure water or air into the heating system to test the tightness and pressure-bearing capacity of the system. This process detects leaks or damage to pipes, valves and connections, ensuring safe operation during the heating season.
2. Steps to suppress heating
| steps | Operation content |
|---|---|
| 1. Preparation | Close all valves in the heating system to ensure the system is closed. |
| 2. Connect the pressing equipment | Use a professional pressure pump to connect to the water inlet of the heating system. |
| 3. Inject water and pressurize | Slowly inject water or air, and the pressure gradually rises to 1.5 times the working pressure (usually 0.8-1.2MPa). |
| 4. Pressure holding test | Maintain the pressure for more than 30 minutes, observe changes in the pressure gauge, and check for leaks. |
| 5. Pressure relief and repair | If a leak is found, repair the problem after the pressure is relieved and repeat the test until there is no leak. |
3. Things to note when suppressing heating
1.Safety first: Avoid overpressure during the pressing process to prevent damage to pipelines or equipment.
2.Gradually increase pressure: Slowly increase the pressure to avoid system shock caused by instantaneous high pressure.
3.Comprehensive inspection: Focus on checking valves, interfaces, radiators and other leak-prone parts.
4.Professional tools: It is recommended to use a professional pressure pump to ensure test accuracy.
4. Common problems and solutions for heating suppression
| question | Possible reasons | solution |
|---|---|---|
| Pressure drops quickly | There is a leak in the system | Check pipe joints, valves and repair them. |
| The pressure cannot rise | The pressure pump fails or the system is not closed | Check the status of the pump and system valves. |
| local water seepage | Aging radiators or pipes | Replace damaged parts or seal. |
5. The best time to suppress heating
It is recommended to perform heating suppression 1-2 weeks before the heating season to avoid conflict with other maintenance work. The following is the discussion data related to the heating crackdown on hot topics in the past 10 days:

6. Summary
Heating suppression is an important step to ensure heating safety in winter. Through standardized testing, problems can be discovered and solved in advance. It is recommended that users follow the above steps or contact professionals for assistance. Regular maintenance can not only extend the life of the heating system, but also improve heating efficiency and keep the family warm during the winter.
