What should I do if the end of the heater is not hot? A summary of popular solutions across the network
With the arrival of winter, lack of heating has become a headache for many families. Especially the end of the heater is not hot, which affects the overall heating effect. This article combines the hot discussions and expert suggestions on the Internet in the past 10 days to sort out a set of system solutions for you.
1. Common reasons why the heater end is not hot
| Reason type | Specific performance | probability of occurrence |
|---|---|---|
| Air blockage | The end radiator is not hot at all | 45% |
| hydraulic imbalance | The further away from the boiler, the less hot it is | 30% |
| clogged pipes | The radiator is partly hot and partly cool | 15% |
| Valve failure | Regulating valve does not respond | 8% |
| Others | System design issues, etc. | 2% |
2. Step-by-step troubleshooting and solutions
Step 1: Exhaust Treatment
This is the most common and easiest solution. Find the exhaust valve on the top of the radiator and turn it slowly with a screwdriver until water flows out, then close it. Make sure to prepare water containers.
Step 2: Check Hydraulic Balance
| Operation | Specific methods | Things to note |
|---|---|---|
| Adjust main valve | Close all valves first and open them one by one from nearest to far | 10 minutes apart each time |
| Balance valve adjustment | Clockwise reduces flow, counterclockwise increases | Make good mark records |
Step 3: Pipe Flushing
For systems that are more than 3 years old, it is recommended to contact a professional to use a high-pressure water gun to flush the pipes and remove internal sediments.
3. Key points in processing different heating systems
| System type | Key measures | Professional advice |
|---|---|---|
| central heating | Mainly exhaust and balance | Don’t release water privately |
| Wall mounted boiler system | Check water pump pressure | Maintain 1.5bar pressure |
| Floor heating system | Divider adjustment | Individual exhaust for each channel |
4. Some effective tips tested by netizens
1. The "tapping method" on Douyin Heat Transfer: Use a rubber hammer to gently tap the pipe to help the air bubbles move
2. The "temperature adjustment method" hotly discussed on Weibo: first adjust all radiators to the highest temperature, and then adjust after running for 2 hours
3. The "Towel Wrapping Method" recommended by Xiaohongshu: Wrap the non-heated parts with a wet towel to help heat conduction
5. When does it require professional maintenance?
If the problem is still not solved after trying the above methods, it may be due to the following situations, and it is recommended to contact a professional:
- Heating system has not been maintained for over 10 years
- Hear obvious abnormal sound of water flow
- Multiple sets of radiators are not hot at the same time
- Water leakage occurs
6. Preventive measures
| time | maintenance items | Operational points |
|---|---|---|
| Before heating every year | System check | Trial run 2 weeks in advance |
| During heating | Exhaust gas regularly | 1-2 times a month |
| After stopping heating | Full water maintenance | Maintain system pressure |
Through the above systematic analysis and solutions, I believe it can help you effectively solve the problem of no heat at the end of the heater. Remember, regular maintenance is key to maintaining effective heating.
