How to suppress floor heating
Floor heating pressure is an important step after floor heating installation or repair. Through pressure testing, it is ensured that the system has no leaks and is operating normally. The following is a detailed guide on the suppression of floor heating, compiled based on the hot topics and hot content on the Internet in the past 10 days.
1. Basic process of floor heating suppression
Floor heating suppression is usually divided into the following steps:
| steps | Operation content | Things to note |
|---|---|---|
| 1. Preparation | Close all valves and check whether pipe connections are secure | Make sure the system is at rest |
| 2. Water injection and exhaust | Fill the system with water and open the exhaust valve to remove air | Until the water flow is stable and bubble-free |
| 3. Pressure test | Use a pressure pump to increase the pressure to 1.5 times the working pressure | Keep pressure on for at least 24 hours |
| 4. Check for leaks | Observe changes in the pressure gauge and check whether there is leakage in the pipeline interface | If the pressure drop does not exceed 0.05MPa, it is qualified. |
| 5. Pressure relief recovery | After the test is completed, slowly release the pressure and restore the system to normal status. | Avoid shock caused by rapid pressure relief |
2. Frequently asked questions about floor heating suppression
Based on recent hot discussions on the Internet, the following common problems and solutions have been compiled:
| question | Possible reasons | Solution |
|---|---|---|
| Rapid pressure drop | Pipe leaks or valves not closed tightly | Check the interfaces one by one and use soapy water to detect leaks |
| The pressure cannot rise | The pressure pump is faulty or the system exhaust is not clean. | Check the pressure pump and re-exhaust it |
| Not hot locally | Pipe blockage or air lock | Flush pipelines in sections to enhance exhaust |
| Pressure gauge pointer shakes | There is air or water hammer effect in the system | Thoroughly exhaust and slowly pressurize |
3. Things to note when suppressing floor heating
1.pressure to choose: The working pressure of general residential floor heating systems is 0.4-0.8MPa, and the pressure should reach about 1.2MPa.
2.time control: The pressure holding time should be no less than 24 hours, and should be appropriately extended to 48 hours during winter construction.
3.Temperature requirements: When the ambient temperature is lower than 5℃, anti-freeze measures should be taken to avoid pipe freeze cracking.
4.Security protection: During the pressing process, keep away from the pipe joints to prevent high-pressure water from splashing and injuring people.
5.record keeping: Detailed record of various data during the suppression process as a reference for future maintenance.
4. Professional advice on floor heating suppression
1. It is recommended that professionals perform the suppression operation. Non-professionals should not attempt it without authorization.
2. The newly installed floor heating system should undergo the first pressure test before the decoration is completed.
3. It is recommended to conduct a routine pressure test before the heating season each year.
4. If you find that the pressure drops abnormally, you should contact a professional for repair in time.
5. Choose pressure gauges and pressure equipment with reliable quality to ensure accurate test results.
5. Recent hot topics of discussion
According to network data analysis, hot topics about floor heating in the past 10 days have mainly focused on:
| topic | Attention | Main content |
|---|---|---|
| The relationship between floor heating cleaning and suppression | high | Discuss whether re-pressure is needed after cleaning |
| Intelligent floor heating pressure monitoring system | in | Application of new intelligent pressure monitoring equipment |
| Floor heating suppresses DIY feasibility | high | Netizens share experiences and lessons learned from self-suppression |
| Floor heating pipe material and pressure bearing capacity | in | Pressure test standards for pipes made of different materials |
Through the above content, I believe you have a more comprehensive understanding of floor heating suppression. Correct floor heating pressure operation can ensure the safe and stable operation of the heating system and avoid problems in later use. If you have any questions, it is recommended to consult a professional floor heating installation company for more detailed technical guidance.
