What should I do if the heaters connected in parallel are not hot? Comprehensive analysis of causes and solutions
As winter approaches, lack of heating has become a focus issue for many families. Especially users who use parallel systems are often troubled by uneven heating. This article will combine the hot discussions on the entire network in the past 10 days, analyze the common reasons why parallel heaters are not hot, and provide structured solutions.
1. Common reasons why heaters connected in parallel are not hot
| Cause classification | Specific performance |
|---|---|
| hydraulic imbalance | Some radiators have insufficient flow, resulting in uneven heating and cooling. |
| clogged pipes | Impurity deposition affects hot water circulation |
| Air blockage phenomenon | Air accumulation in pipes blocks water flow |
| Valve failure | The regulating valve is damaged or not fully opened |
| System design flaws | The length difference of parallel pipelines is too large |
2. Targeted solutions
1.Hydraulic imbalance adjustment: Balance the flow distribution by adjusting the opening of each branch valve. It is recommended to give priority to closing the valve of the hottest radiator and gradually adjust it until the temperature of all radiators is uniform.
2.Pipe cleaning: If you suspect it is clogged, you can use professional cleaning agents or contact the property management company for high-pressure flushing. The following are statistics of common congestion locations:
| blocking position | probability of occurrence |
|---|---|
| Radiator water inlet | 45% |
| parallel branch corner | 30% |
| Main return pipe | 25% |
3.Exhaust operation: Use the exhaust key to open the exhaust valve on the top of the radiator until clean water is discharged. Note: The floor heating system needs to be exhausted through a water distributor.
4.Valve inspection: Confirm that all valves are open and replace the damaged temperature control valve. Recommended valve type priority:
| Valve type | Applicable scenarios |
|---|---|
| Automatic thermostatic valve | Precise temperature control requirements |
| Manual regulating valve | Economical solution |
3. Preventive measures and advanced suggestions
1.Regular maintenance: Clean the filter before the heating season and fully flush the pipes every 2-3 years.
2.System upgrade: If it is an old system, consider installing a circulation pump or changing to an octopus-type water distributor system.
3.Professional diagnosis: For complex problems, it is recommended to use a thermal imager to detect the status of the pipeline and accurately locate the fault point.
Through the above methods, 90% of the problems of parallel heaters not getting hot can be effectively solved. If it still cannot be improved, you should contact the heating company or professional maintenance personnel to investigate in time.
