One of the most common heating issues experienced by homeowners is their radiators losing efficiency and failing to get as hot as they once did. If this has happened to you, and you want to know why read on.
Something has gone wrong with your boiler
If your radiators are cooler than you’re used to and you are having other issues like strange noises or cold water that should be hot water, it may indicate that you have a boiler problem that will need to be sorted by a qualified heating engineer for your own safety.
There’s air trapped in the system
Heating systems can sometimes suffer from trapped air, which can cause your radiators to be less efficient because only the bottom portion will get hot. The good news is you can fix this yourself by simply bleeding your radiators. If that doesn’t solve the problem, you will probably need to call a plumber, though.
Check the valves
Sometimes, valves can be turned off accidentally or become stuck rendering them useless. Check all of your valves are open, and that the thermostatic valve is turned on. If the valve is stuck, you may need a plumber to fit a replacement.
There’s sludge in the system
If the radiator is only heating up at the top, there could be sludge in the system, which a qualified heating engineer will be able to flush out.
