The Ultimate DIY Guide on How to Bleed a Radiator
Radiator are
a great way to heat up your home especially in the winter. However, as with any
system that runs some form of liquid through them, internal buildups can form
in the radiators. These buildups can have a drastic effect of the performance
of the radiators. This means you will need to bleed your radiator. Bleeding
radiators is the process of releasing any trapped air inside the radiator
that causes cold spots and reduces
efficiency.
How Often Should You Bleed Your Radiators?
Bleeding
the radiators should not be done too frequently as there is simply no need. It
is recommended that you should bleed your radiators, once a year. The best time
to do this is in the autumn as you will need your radiators to be up and
performing as winter approaches.
What do You need to Bleed Your Radiator?
Here are a
few things you will need bleed your radiator:
1. You will
need a radiator key / flat screwdriver. You will need a flat screwdriver only if
you don’t have a radiator key.
2. You will
need 2 rags.
3. You will
need a bucket or any container for collecting water.
A Step-By-Step Guide to Bleeding a Radiator
Here's how
you can bleed a radiator in 7 easy steps:
Step 1: Diagnosing the issue
If your
radiator is taking too long to heat up, or you can feel cold patches across the
radiator usually at the top, you will need to bleed to radiator. The cold
patches are caused by trapped air or gas.
Step 2: Identify the radiator with the issues
Turn your heating
fully on and allow your radiators time to reach full heat. Your radiator should
be hot before you bleed it. Assess each radiator for cold patches and figure
out which radiators need bleeding. As radiators can get very hot, you should be
careful when checking them.
Step 3: Turn the heating off
It is
critical that you turn the heating off once you have identified the radiator
with the issue. If you don’t do this, you will end up with a lot of water on
the floor all around your home.
Step 4: Release the air
Take your
radiator key and fit it to the valve at the top of the radiator (aka radiator
valve). You should wrap one rag around the key. You should do this to protect
your hands from the hot air that will escape. You should then hold the other
rag below the valve to catch any water that drips out and place your bucket
underneath the valve for extra spillage. You should then twist the key slowly
anticlockwise to release air. You should be able to hear the air or gas escaping.
Step 5: Close the valve
When you
aren’t able to hear the air escaping, the trapped air has been released from
the radiator. Now, you should quickly turn the valve clockwise. You should do
this as quickly as possible to ensure that no water rushes out. You should not
over-tighten your radiator bleed valve as this may damage your radiator.
Step 6: Test run
Now that
you have bled the radiators, you should perform a test run. Turn your heating
on, wait for your radiators to power up, and check that all previous cold spots
have now gone.
Step 7: Persistent issue
If the
issue still persists, you should turn off the heating and repeat the process.
