What should I do if the floor on the top floor is not warm? ——Cause analysis and solutions
With the arrival of winter, many owners living on the top floor have reported the problem of insufficient floor heating. This article will combine hot topics and user feedback from the entire Internet in the past 10 days to analyze the reasons why the attic floor heating is not hot, and provide detailed solutions.
1. Common reasons why the attic floor heating is not hot

| Cause classification | Specific performance | Frequency of occurrence (last 10 days) |
|---|---|---|
| Insufficient system pressure | The overall heating effect is poor and the water temperature is low | 35% |
| clogged pipes | It is not hot locally and the temperature difference is obvious | 28% |
| Poor thermal insulation performance | Rapid heat dissipation and difficulty maintaining temperature | 20% |
| Design flaws | Unreasonable pipeline layout and poor circulation | 12% |
| other reasons | Thermostat failure, valve not open, etc. | 5% |
2. Targeted solutions
1. Insufficient system pressure
Check the heating system pressure gauge, the normal value should be between 1.5-2.0Bar. If the pressure is insufficient, you need to contact the property management company to replenish the pressure. Also check whether the automatic exhaust valve is working properly.
2. Pipe blockage
Here are some steps you can try:
| Operation steps | Specific methods |
|---|---|
| Backwash | Close the inlet and outlet valves and use professional equipment to flush them |
| chemical cleaning | Use special cleaning agents to circulate and clean pipes |
| Physical unblocking | Partially clear severe blockages |
3. Poor thermal insulation performance
Rooftop users can take the following insulation measures:
- Check the window seals and install sealing strips if necessary
- Add insulation under the floor (e.g. extruded board)
- Consider installing double glazing or thermal curtains
4. Design flaws
If it is a system design problem, it is recommended to:
- Contact a professional HVAC company to redesign the piping
- Install a circulation pump to improve hot water circulation
- Consider changing to room control to optimize heat distribution
3. Preventive maintenance suggestions
| maintenance items | Recommendation cycle | Things to note |
|---|---|---|
| System pressure check | 1 time per month | Key inspections before and after the heating season |
| Pipe cleaning | every 2-3 years | It is recommended that professionals |
| Exhaust valve inspection | quarterly | Pay attention to whether there is any water leakage |
| Thermostat Calibration | 1 time per year | Completed before heating season |
4. Sharing of actual cases from users
Based on feedback from the network platform in the past 10 days, typical solution cases have been collected:
| Problem description | solution | Effect evaluation |
|---|---|---|
| Are the floors in the three bedrooms on the top floor heated? | Install a circulation pump and rebalance the system | Temperature rises 4-5℃ |
| The temperature rises slowly after the floor heating is turned on | Add insulation layer and replace thermostat | Heating time shortened by 30% |
| Local area is always not hot | Professional pipe cleaning and manifold replacement | Problem completely solved |
5. Professional advice
1. When encountering the problem of non-heating floor heating, it is recommended to conduct simple troubleshooting first (check valves, pressure, etc.), and then contact professionals if the problem cannot be solved.
2. Rooftop users can consider strengthening insulation measures during renovation to solve the problem from the source.
3. When choosing floor heating cleaning services, be sure to confirm the service provider’s qualifications to avoid using inferior cleaning agents to damage the pipes.
4. When reactivating a floor heating system that has not been used for a long time, it is recommended to perform system inspection and necessary maintenance first.
Through the above analysis and solutions, we hope to help top floor users effectively solve the problem of insufficient floor heating and spend a warm winter.
