2. Common causes and solutions for water that is not hot
According to the experience shared by professional maintenance personnel and netizens, lukewarm water is usually caused by the following reasons:
| Question type | Specific performance | Solution | Operation difficulty |
|---|---|---|---|
| Air blockage | Some radiators are not hot/there is a sound of running water | Deflate the exhaust valve until water comes out | ★ |
| clogged pipes | Overall temperature is low | Professional pipe cleaning or replacement | ★★★ |
| Not enough pressure | Poor system circulation | Check booster pump/water replenishment valve | ★★ |
| Temperature control failure | Unable to adjust temperature | Replace the temperature control valve or main board | ★★★ |
| system imbalance | The far end is not hot and the near end is too hot. | Adjust the valve opening of each circuit | ★★ |
3. Step-by-step self-examination guide
1.basic check: Confirm that the main valve of the heating system is open and check whether the pressure gauge is within the normal range of 1.5-2bar.
2.Exhaust operation: Use a flat-blade screwdriver to turn the exhaust valve counterclockwise (usually on the upper right corner of the radiator). If you hear a "hissing" sound, it means exhaust is being released. Close it immediately after the water is stable.
3.Temperature test: Compare the temperature differences of different radiators to determine whether the system is imbalanced. It is recommended to give priority to closing the water inlet valve of the hottest radiator to allow hot water to flow to the far end.
4.Pipeline inspection: Touch the main pipe temperature. If the home pipe is hot but the indoor system is not, the filter may be clogged. You need to close the valve and clean the filter.

1. It is still not hot after exhausting the air several times, and the temperature of the main pipe is normal.
2. Water seepage or obvious corrosion is found at the pipe joints
3. System pressure continues to be lower than 1bar
4. The temperature control panel displays an abnormal code
5. The floor heating system has not been cleaned for more than 3 years.
6. Preventive maintenance suggestions
• System pressure test 1 month before heating season
• Professional duct cleaning every 2 years
• Install water filters to extend equipment life
• Keep the system full of water during non-heating seasons
• Consider installing a smart temperature control system to improve energy efficiency
Through the above structured analysis and solutions, we hope to help you quickly locate the reasons why the water is not hot and take effective measures. If the problem persists, it is recommended to contact a certified HVAC engineer for professional diagnosis.
