4 Warning Signs Your Radiators Need to be Bled
As you probably already know, most homes are kept warm by heating systems that circulate hot water from the boiler through the radiators. However, small air bubbles can get into that system over time. This can occasionally be due to water leaking out, but it's also something that happens naturally as the metal expands and contracts over time.
Those small air bubbles shouldn't be a huge problem right away, but they can lead to oxidisation within your heating system and eventually need expensive boiler repairs. Luckily, you can easily remove the air or have a plumber do it for you by bleeding your radiators.
Here are just four common signs your radiators should be bled.
The Tops of Your Radiators Are Cold
Probably the most common sign your radiators need to be bled is that the top of one or more remains cold, even with the heating on. When air gets into the system, it naturally gathers towards the top of the radiators. This blocks the hot water and prevents the radiator from getting hot all over. If you notice the top of one or more radiators is cooler than the bottom, it probably needs to be bled. If the whole radiator is cold, it's probably a more serious issue with your heating system that should be addressed by a plumber.
You Notice Strange Noises from Your Heating System
Next time you turn on your central heating system, make sure you take note of any noises it makes. If you hear anything that sounds like gulping, gurgling, ticking or rattling, it could be caused by air that is trapped in the system. This could also be a sign of other issues, so it's worth calling a professional if the sounds don't cease once the radiators have been bled.
You Find Unexplained Damp Spots
Most people only think of how a heating system keeps themselves warm, but it's also responsible for preventing moisture in the air from settling on cold surfaces. When this happens, surfaces can be damaged and mould patches can form. If you notice any such damp spots in rooms that have radiators, it's a sure sign your radiators are not working as effectively as they could be.
Your Energy Bills Are Rising
Finally, keep in mind that anything that makes your heating system work harder is going to impact your energy bills. If there's air in the system, you'll have to run the boiler more to maintain the same comfortable temperatures you're used to, so simply taking care of a simple task like bleeding your radiators could help you save money.
