|---|---|
| clogged pipes | Some radiators are hot, some are not. |
| Insufficient water pressure | The overall temperature of the radiator is low |
| gas accumulation | The upper part of the radiator is not hot, but the lower part is hot |
| Valve failure | The radiator is not hot at all |
2. Solutions to the problem of parallel heaters not getting hot
For the above reasons, we can take the following measures:
| question | Solution |

| question | Answer |
|---|---|
| Why is the heater still not hot after exhausting the air? | It may be that the pipe is blocked or the water pressure is insufficient. Further inspection is required. |
| Does parallel heating require exhaust from each radiator? | Yes, every radiator can accumulate gas |
| What should I do if the radiator is half hot and half not hot? | Try exhausting air first. If it doesn't work, the pipe may be clogged. |
5. Professional advice
If you still cannot solve the problem after trying the above methods, we recommend:
