Keeping warm during winter is essential and having a working radiator is the key. However, some problems can occur disturbing the efficiency of your radiators. This article will explore common radiator problems and provide simple solutions that you can do at home. 

Problem 1: Cold at the Bottom

If only the top part of the radiator gets warm, it can be a sign that there is air in your system known as ‘bleeding’. Bleeding the radiator can solve this problem. It involves opening the bleed valve to let out any air trapped in the system. Once water starts flowing out, you should close the valve. However, remember to shut-off the central heating before you start, to avoid burns or scalding.

Problem 2: Cold in the Middle

Sometimes, radiators may produce heat only at the top and the bottom but stay cold in the middle. This generally signals a build-up of sludge or rust in the radiator. You can address this issue by flushing the radiator, an activity which entails draining the central heating system and adding a cleaning agent to eliminate the sludge.

Problem 3: Cold at the Top 

When your radiator is cold at the top but warm at the bottom, it might indicate that there is air in your heating system. Similar to the first problem, bleeding the radiator will resolve this. However, if bleeding does not improve the situation, the problem could be due to inadequate water pressure in your boiler. For this, you might want to consider professional help.

Problem 4: Noisy Radiator

Radiators shouldn’t have to make too much noise to keep you warm. If you experience creaking, whistling or banging noises, air could be trapped in the system. However, also consider the water pressure, as low pressure can similarly be the cause. If the noise persists, it might be time to call in a heating engineer.

Problem 5: Leaky Radiator

Radiators can sometimes leak water. This can be due to internal corrosion or damage to the valves. Gauging the threat of a leaking radiator can be difficult, and if left untreated, it might result in unnecessary water expenditure or further damage to your home. Therefore, it might be wise to seek professional help for this problem.

Final Thoughts

Anytime you face issues with your radiator, it’s best to diagnose the problem to get a better understanding. With some simple troubleshooting, you can fix several common radiator problems. However, for severe issues and if you are not comfortable doing these DIY fixes, don’t hesitate to call a professional heating engineer. Remember, a functioning radiator is crucial to keep your home warm and comfortable, particularly during the cold winter months.
