Noisy Radiators?

Bubbling noises from radiators are quite a common issue but dealing with this problem does not necessarily require any specialist technical expertise, and you may be able to stop the annoying noisy and bubbling in a few minutes with the right tools and the right advise, before having to us the experts in.

So, if you have a noisy radiator and are hearing gurgling or bubbling noises, the following guidance could help you resolve the problem without calling us, Ability plumbers.

Most of the components that make up your central heating system are made from metal, and metal, as you probably already know, will expand and contract as it heats up and cools down. So, it may be that the sounds you hear your central heating make are just being caused by that natural process. Because pipework creaks and groans as it expands and contracts, it can be something that you get used to, but if your central heating is making strange noises, it’s best not to ignore it.

Loud Heating Systems

More serious causes of annoying and loud central heating should be thoroughly investigated and fixed by us at Ability plumbing, with the worst-case scenario being that you have to part with a little bit of money to get it sorted. But here at Ability, we like to give you any help and guidance as well as the right information to fix things for yourself, so this post is designed to help you identify the most common causes of noisy heating systems to help you to solve the problems without having to splash the cash on expensive repair bills. If its something simple and we can help, then we will.

Increase the water pressure

Sometimes, a central heating system needs an extra push to get air out of radiators. Make sure your circulation pumps are on, turn up the water pressure to around two bars, and then bleed the radiator again.

Check the pumping system

Is your pump working correctly? Is the vent on the pump’s suction side? Is your pump speed right or is it too high If the gurgling stops when you turn your pump off, then you may have isolated the problem – repairing it, however, could be a trickier task.

As always, do not attempt to repair your boiler or central heating system if you are unsure of what to do. If a repair involves taking a gas boiler cover off, then it is too complicated for a layperson and you need to get in touch with us here at Ability and we will send an engineer.

Bleed the radiators

A noisy radiator is likely to have air trapped inside it. An easy way to diagnose this problem is to feel the radiator when it is turned on – if it is hot at the bottom but cold at the top, then it needs bleeding.

It might seem obvious but bleeding your radiators could be all it takes to expel this air, stop the radiator noise and allow you to enjoy a near-silent central heating system once more. You simply need a radiator key to let the air out.

If you find yourself bleeding your radiators more regularly than you think is usual, then there is probably a leak in your central heating and plumbing system somewhere. You could add some anti-corrosion inhibitors into the central heating system when the leak has been repaired to ensure the problem does not repeat itself.
