If your central heating isn’t working as efficiently as you would like, it could be a sign that you need to bleed your radiators.
Bleeding your radiators regularly helps to remove air which is trapped in the central heating system. If air is present, there is less space for the hot water and this will prevent the radiator from heating up correctly.
With air trapped in your central heating system, you will find it takes longer to heat up your home and it might never feel warm enough. It will cost more for you to heat your home and it will make your home less environmentally friendly.
The top of the radiator is cold
Turn your central heating on and wait for it to warm up. Now check your radiators. Does the temperature at the top of your radiators feel the same as the temperature at the bottom of your radiators?
If it’s cold at the top of the radiator, this is a classic sign that you need to bleed your radiators. It might not be completely cold. Sometimes the top is just warm while the bottom is hot.
The entire radiator is cold
First, check that the lock-shield radiator valve is open by turning it as far as you can anti-clockwise then check the pipes going into the radiator by placing your hand on them.
If this has resolved the issue, one of the pipes should start to feel warm. If this hasn’t helped, check the thermostatic valve is moving properly.
Take the cap off the thermostatic valve and push the pin down. This should be moving freely. If it’s stuck and not moving freely you may need to have a replacement thermostatic valve.
Strange noises from your heating
When your heating first turns on, does it make noises similar to gurgling or rattling?
This can be a sign that air is trapped in the system although it could also be an indication of various other issues too.
So, checking the radiators is a must to make sure the problem is not more serious.
If you bleed your radiators and the problem persists, then you may need to call a professional to diagnose the issue.
Having all your radiators working as they should be will make your home more comfortable, help you to save money on heating bills.
