An Airlock In Radiator Can Be So Annoying.

By: Kane Ashley

If your radiator ever feels cold at the top and warm at the bottom then it is more than likely that your problem is being caused by air which has been trapped inside your radiator. Fortunately, you should be able to fix the problem yourself by bleeding your radiator. Another option for you is to call out a plumbing and heating engineer. However bleeding a radiator is usually a fairly simple, safe and quick process if it is done the correct way. Ultimately it just requires opening a tiny valve on the top of your radiator to allow any trapped air to escape. Just follow the simple instructions below for a fast and lasting repair:

Prior to bleeding your radiator, it's very important that you shut down your central heating at the main controls. It will avoid any more air from entering the heating system. Find the bleed valve; this more often than not has a small red coloured handle and is situated on one side of the radiator when it was bought.

Place a cloth or a medium sized bowl underneath the bleed valve to catch any leaking water. Cover your hand in a cloth to shield your hand as any water that escapes from the radiator may be very hot. Your radiators should have come with a tiny bleed key (or radiator key). In case you cannot find the bleed key you should be able to buy a replacement at your local DIY store.

First you will have to find the bleed valve, this will be a protrusion at the top of one side of your radiator. To bleed your radiator, place the bleed key onto the valve and carefully turn it anticlockwise (usually a quarter to half a turn will do the trick). The air trapped in your radiator will start escaping with a hissing sound. At this stage you may have to switch on your heating for a short time to keep the pressure up in the system. When you are bleeding your system you also have to keep an eye on your water pressure level. When water begins to dribble out of the valve this is how you know that all of the air has been purged from your radiator.

As soon as water starts to dribble out of your valve make sure you tighten the valve back to it's original position. Go to your main control panel and check your water pressure leve. This level needs to be set at manufacturers levels. Use the cloth to clean up any spills (at this point be cautious as the water can be scalding hot). Remember to switch the central heating back on once you've finished bleeding the radiator. Check on your radiator after a couple of hours to ensure that the radiator has a uniform temperature all over it's surface area and that there is no more water leaking out of your bleed valve. Hopefully this will mean that your problem is solved!

Remember, if you're ever unsure of your DIY abilities, then it is better to call in a plumbing and heating engineer to mend the problem for you.

I have spent a lot of my time working for a company called Boiler Repair London and I have seen some pretty sites and some not so pretty sites. Over the years I have realised that there is a lot can be done to avoid calling out a plumber or gas engineer to solve small problems.
