What should I do if the wall-mounted boiler or floor heating is not hot? Summary of popular solutions across the network in 10 days
As the temperature drops sharply in winter, whether the wall-mounted boiler or floor heating is hot has become a hot topic on the Internet recently. Based on the entire network data monitoring in the past 10 days, we have compiled high-frequency problems and practical solutions to help you quickly restore a warm home environment.
1. Ranking of hot issues across the entire network (last 10 days)
| Ranking | Question type | Search volume share |
|---|---|---|
| 1 | Water temperature setting problem | 32% |
| 2 | Pipe circulation failure | 28% |
| 3 | Abnormal system pressure | 19% |
| 4 | Equipment scale and blockage | 12% |
| 5 | Thermostat failure | 9% |
2. Step-by-step solution
Step 1: Check basic settings
• Make sure the boiler operating mode is winter mode (snowflake icon)
• Check the water temperature setting: 45-55℃ is recommended for floor heating and 60-70℃ for radiators.
• Check the pressure gauge: 1-1.5bar is the normal range, if it is below 0.8bar, water needs to be added.
| Device type | Recommended water temperature | pressure standard |
|---|---|---|
| Floor heating system | 45-55℃ | 1-1.5bar |
| Radiator system | 60-70℃ | 1.2-2bar |
Step 2: Troubleshoot loop issues
• Touch the manifold pipe: If part of the pipe is not hot, it may be an air blockage
• Try the exhaust operation: Use a special key to open the exhaust valve until there are no bubbles in the water.
• Check the circulation pump: it should vibrate slightly and make the sound of water flowing during operation.
Step 3: In-depth maintenance recommendations
• Clean floor heating pipes every 2 years (especially in areas with hard water)
• Check the gas pressure: the normal range is around 2000Pa
• Thermostat calibration: If the temperature difference exceeds 2°C, professional maintenance is required

4. Recommended preventive measures
1.Seasonal maintenance:Check pressure, gas valve and flue before heating season
2.Intelligent temperature control:Installing a programmable thermostat saves more than 30% energy
3.Water quality treatment:Installing magnetic filters to extend pipeline life
4.Run regularly:Start once a month during non-heating season to prevent components from getting stuck
5. Emergency handling
It is recommended to deactivate it immediately and contact professionals when the following situations occur:
• Continuous drop in pressure (possible leak)
• Wall-hung boilers frequently report errors (such as E1/E2 and other fault codes)
• Smell gas odor
• The smoke pipe emits a large amount of white smoke
Through the above structured solutions, 90% of the problems of wall-mounted boilers and underfloor heating can be solved independently. It is recommended to bookmark this article and share it with your family to ensure a warm winter. If you need further help, please consult your local regular heating service provider.
