Most of the warmth in your home during the winter months comes from radiators. But if one of them is not working properly, there are a few common issues to look for.
Sludge build up can cause parts of your radiator to not receive warm water thus causing cold spots. But knowing how much sludge or how bad the problem is can be tricky. An infrared camera can be used to map out the cold areas and get a better idea of the sludge problem. Fixing the problem is done by having a professional come in and power flush your radiators, cleaning out the sludge and creating a more even water flow throughout your radiator.
Trapped air can be a nuisance, but with the right tool and a bit of patience (depending on your heating system), it can be as easy as simply bleeding your radiator to allow the air out. First and foremost, if in doubt, call a professional, turning the key too far can cause flooding. Simply turn the key, allow the water flow to push out excess air and close the valve.
A faulty radiator can be a bit more of a challenge, as replacing the radiator in some cases is the only option. First make sure a heating engineer checks all valves for leakage. If there is a normal water flow into your radiator, but you are still not getting warmth throughout the radiator, there may be issues internally that would need to be addressed.
The below video shows how the water should flow through your radiator to create an even heat:
