What should I do if the floor heating pressure is not enough? ——A complete guide to cause analysis and solutions
Recently, the temperature has dropped sharply in many places, and the use of floor heating has become a hot topic. Many users reported that the heating effect of floor heating in their homes was poor. After inspection, it was found that the problem was caused by insufficient system pressure. This article combines the hot discussions on the Internet in the past 10 days to systematically sort out the common causes and countermeasures of insufficient floor heating pressure.
1. Common symptoms of insufficient floor heating pressure
| Symptoms | frequency of occurrence | Related questions |
|---|---|---|
| The floor is not hot locally | 67% | Poor water circulation |
| Frequently refill the system | 42% | Pipe leaks |
| Boiler starts and stops frequently | 35% | Pressure sensor failure |
2. Six major reasons for insufficient stress
| Cause classification | Proportion | Typical characteristics |
|---|---|---|
| Pipe leaks | 38% | The pressure gauge continues to drop |
| Automatic exhaust valve failure | 22% | There is a sound of water flowing in the pipe |
| Expansion tank failure | 15% | Severe pressure fluctuations |
| Water replenishment valve clogged | 12% | Replenishing water is extremely slow |
| Pressure sensor failure | 8% | The displayed value does not match the actual value |
| No exhaust during installation | 5% | Newly installed system is not hot |
3. Step-by-step solution
1.preliminary inspection: First observe the pressure gauge, the normal range should be 1.5-2.0Bar. If it is lower than 1.0Bar, it needs to be dealt with immediately.
2.Check for leaks: Focus on checking the water distributor interface and floor heating pipe connection. You can try wiping suspected leaks with paper towels to see if there are any water stains.
| Check site | Leakage probability | Processing method |
|---|---|---|
| Water distributor interface | 61% | Replace sealing ring |
| Floor heating pipe connection | 28% | Re-hot melt connection |
| Wall penetration part | 11% | Repair waterproof layer |
3.System hydration: Close the main valve, open the water supply valve and slowly inject water to 1.5Bar, and pay attention to the pressure changes.
4.Exhaust treatment: Open the water distributor exhaust valve in sequence until continuous water flow is discharged. It is recommended to use professional exhaust tools.
4. Professional maintenance suggestions
1. A system pressure test should be conducted every year before the heating season to detect potential problems in advance.
2. Install an automatic pressure alarm device to provide timely reminder when the pressure is lower than 1.0Bar.
3. It is recommended to replace the expansion tank every 3-5 years to avoid pressure instability due to aging.
5. Common misunderstandings among users
| Wrong operation | possible consequences | Correct way |
|---|---|---|
| Frequent manual hydration | Accelerate system corrosion | Identify leaks and deal with them |
| Adjust the pressure yourself | Pipe burst risk | Keep 1.5-2.0Bar |
| Ignore minor leaks | Cause floor deformation | Timely and professional maintenance |
6. Emergency treatment plan
If you notice a rapid drop in pressure:
1. Immediately close the system main valve
2. Cut off the power supply to the boiler
3. Contact professional maintenance personnel
4. Record the pressure drop rate (helps to determine the location of the leak point)
Through the above systematic analysis and solutions, we hope to help you effectively deal with the problem of insufficient floor heating pressure. It is recommended to bookmark this article and follow the steps to troubleshoot if you encounter problems. If the problem persists, be sure to contact professional floor heating maintenance personnel for inspection.
