Radiator Not Getting Hot Even After Bleeding
One possible reason for a radiator failing to heat up, despite being bled, is a stuck pin on the thermostatic radiator valve (TRV). The TRV can be identified as the bulkier of the two radiator valves indicating temperature control settings. Removing the cap/head on the TRV can help determine if this is the cause of the problem.
A possible reason behind the radiator not getting hot despite bleeding is a potential malfunction of the thermostatic radiator valve (TRV), particularly a jammed pin. The TRV is identifiable as the larger valve controlling the temperature settings, often with a cap/head covering it. To determine if a stuck pin is at fault, one may remove the TRV cap/head and inspect the valve.

Why is only one of my radiators not heating?
There are several potential reasons why only one radiator in your heating system is not heating up. One possibility is that there may be air pockets trapped within the radiator or the surrounding pipes, which can hinder proper circulation of hot water. Another potential cause could be a leak or blockage within the specific radiator, preventing heat from flowing through it effectively. Additionally, there may be a malfunction in the radiator's thermostat, preventing it from properly regulating the flow of hot water. In any case, it is important to address the issue promptly in order to restore proper heating function and prevent any further damage to your heating system. Depending on the root cause of the problem, some solutions may be simple and can be addressed by the homeowner, while others may require the assistance of a qualified professional.
Do radiators need to be balanced?
In large heating systems, radiators may need to be balanced if they are not getting enough heat. This can be done by partially closing the lockshield radiator valves to distribute heat evenly.
Do I need to bleed my radiators?
If your radiators are warm at the bottom but cold at the top after turning the heating back on, air may be trapped in them. Bleeding your radiators can solve this issue. Unscrew the bleed screw with a radiator key until you hear a hissing sound. These are the five steps to take when your radiators won't heat up.
There are several possible reasons why radiators may not be getting hot. These include the presence of debris in the pipework or filter, a circulation pump that is not functioning or has accumulated air, air in the heating system, a malfunctioning thermostatic radiator valve (TRV), a lockshield that has been fully opened or closed, a boiler or heat pump that is not working properly, a central heating system that has been turned off, or a depleted fuel source.
