As a heating system expert with years of experience in troubleshooting and maintaining radiators, I can provide you with a comprehensive answer to your concern about why your radiator may not be heating up. There are several reasons why this might be happening, and I will outline the most common issues and their solutions.
Firstly, it's important to check if the heating system is turned on and set to the correct temperature. This might seem obvious, but it's a simple step that's often overlooked. Ensure that the thermostat is set to a temperature above the current room temperature and that your heating system is activated.
Air in the System: One of the most common reasons for a radiator not heating up is trapped air. Air can accumulate in the radiator and prevent hot water from circulating properly. To resolve this issue, you will need to bleed the radiator. This involves using a radiator key or a similar tool to open the bleed valve, allowing the air to escape and the water to flow freely. Start by turning the valve counterclockwise until water begins to drip out. You may hear a hissing sound as the air escapes. Once water starts to flow steadily, close the valve.
Boiler Issues: If the boiler is not functioning correctly, it can affect the entire heating system. Check to see if the boiler is on and if it's displaying any error codes. If it is, consult the boiler's manual or contact a professional to address the issue. Regular maintenance of the boiler is crucial to ensure it operates efficiently and safely.
Circulation Problems: Poor circulation can also lead to a radiator not heating up. This could be due to a partially closed valve, a blockage in the system, or a malfunctioning pump. Inspect the valves to make sure they are fully open. If you suspect a blockage, you may need to flush the system or have it inspected by a professional.
Thermostat Settings: The thermostat controls the temperature of your home and can affect the operation of your radiators. If it's set too low or not working properly, your radiators may not heat up. Ensure that the thermostat is functioning correctly and is set to an appropriate temperature.
Heat Distribution: Sometimes, the issue is not with the radiator itself but with how heat is distributed throughout the home. Insufficient insulation, open windows, or doors can cause heat to escape, making it seem like the radiator is not working when it actually is. Check for drafts and ensure that your home is well-insulated.
Radiator Age and Condition: Over time, radiators can become less efficient. If your radiator is old or has not been maintained, it may not heat up as well as it used to. Regular cleaning and maintenance can help, but eventually, you may need to consider replacing an old radiator.
Water Pressure: Low water pressure in the heating system can also prevent a radiator from heating up. The boiler needs sufficient pressure to push hot water through the system. Check the pressure gauge on your boiler and adjust it if necessary.
Radiant Efficiency: The efficiency of a radiator can be affected by its design and the materials it's made of. Some radiators may not heat up as quickly or as evenly as others. If you've ruled out all other issues and your radiator is still not heating up, it may be worth considering an upgrade to a more efficient model.
In conclusion, there are various factors that can cause a radiator not to heat up. By systematically checking each potential issue and applying the appropriate solution, you should be able to resolve the problem. If you're unsure or if the problem persists, it's always best to consult with a professional heating engineer.

With your radiator key, slowly turn the valve counterclockwise until water starts dripping out. If you have a hot-water heat radiator that's not heating the cause is usually trapped air, and getting rid of it is simple. ... Do this by opening, then closing, the valve on the water pipe above the boiler.
