Winters cold enough without your heating not working correctly. That’s why we’ve created a quick guide to what to do if your radiator isn’t heating up in those colder months

In the winter months the last thing you want is a cold house that you can’t quite warm up. Thankfully there are a few simple steps that you can take to maintain your central heating and ensure that all radiators are working as you require. Most of the time issues with your radiators can be a simple problem that can be easily resolved, here are 5 simple steps that you can follow and get your home back to that perfect temperature in no time!


  • Are there any bigger problems with your central heating system?


The first thing that you need to do is check that your central heating system has any bigger problems, are all of your radiators off? Do you have hot water? Is your boiler making funny noises?

If so you will need to get a gas safe engineer out as this would indicate that there is a bigger problem with your boiler than your radiators.


  • Do you have any trapped air in your radiators?


Air can become trapped in your radiators, causing them to warm at the bottom but not at the top. If you turn on your central heating and this is the case then you may need to bleed your radiators. You must turn off your radiator to ensure that you are able to work with the temperature of the radiator.

At the top of the radiator at one end there will be a valve. You can attach the radiator key to the square bit in the centre or put the end of the screwdriver into the groove. Hold the key or screwdriver with a cloth, and have another cloth ready to catch any drips, then slowly turn the radiator key or screwdriver anti-clockwise – if gas is escaping you’ll hear a hissing sound. Once there is no more gas, liquid will come out and the valve will need to be closed quickly. With the more modern screwdriver operated escape valve, liquid is likely to emerge as a jet rather than a dribble.

Your radiator should now be nice and warm all over!


  • Check your radiator valves


If bleeding your radiator has not solved the problem, you need to check the valves on your radiator.

Ensure that both valves either side of the radiator are open, and if you have a thermostatic valve (one that allows you to set a specific temperature for your radiator) make sure this is turned on.

It is possible that your valves can seize up, if you think that this is the case then you need to get in touch with a heating engineer who will be able to review the valves and potentially replace the valves if they feel this necassey.


  • You might need to get your system power flushed


Over time your central heating systems can build up sludge and debris that can become stuck within radiators and pipes, this causes the system to not perform at maximum capacity. Powerflushing is a process whereby you can flush out sludge from your system to hopefully bring it back to life!

The normal signs of a system that is heavy in sludge is that your radiators hold more heat towards the top and the bottom of the radiator is cold as this is where the sludge is collating.

When your central heating is on, check all main radiators to see if you have and cold spots – if your radiators are similar to image above on the left then we would recommend that you give us a call on 01514829519 and we can arrange for one of our engineers to come to your property and assess if they believe a power flush on your system would help solve your problems.


  • Get help from a professional gas engineer


If your boiler is still not running to a standard you expect then the best thing we can recommend is that you have a heating engineer take a look at your boiler. You can give us a call on 01514829519 and we can arrange for one of our Gas safe engineers to come to your property so we can provide the best course of action to make your heating more efficient.
