One. Reasons for insufficient heating
1、Reasons for heating system
To check if the heating system is blocked, first touch the pipes connected to the heating system. If the pipes are not hot, it may indicate a blockage in the heating system. The blockage could be caused by the accumulation of scale and sediment due to years of neglect and lack of maintenance of the heating pipes, which increases thermal resistance and restricts water flow.
2、There is air blockage inside the heating pipe.
Check if the system has insufficient flow or if the circulating water contains excessive air. If the radiators are cold to the touch, it may indicate that the radiator drain valve is malfunctioning, causing air to accumulate inside the radiators and preventing them from heating properly. If the radiators make a gurgling sound, it may also indicate that there is trapped air inside the radiators that cannot be discharged.
3. Human-caused
Problems caused by human factors, such as improper venting, draining, unauthorized modifications to the heating system, and failure to pay heating fees, can lead to a lack of heat in the home's heating system. The effectiveness of the heating system is related to various factors, including the product itself, installation, after-sales service, and the user's usual usage habits.
Two. What to do if the radiator is not heating up?
1、Localized temperature difference
If a radiator is not heating up evenly, and when you touch the surface, you feel both warm and cold areas, this indicates that there is air trapped inside the radiator. You can manually remove the air from the radiator.
2、Overall, no heat generation.
If the entire heating system is not working, you need to check the status of the boiler's water, electricity, and gas supply to ensure they are functioning correctly. based on the specific error code displayed, you can then proceed with the appropriate troubleshooting steps.
