Bleeding Your Radiators And Reducing Your Energy Costs

How To Bleed Your Radiators

Slash your energy costs with one simple quick fix

Bleeding radiators is one of the simplest ways that you can improve the efficiency of your heating system. In order to bleed the radiator you need to release excess air which may be trapped inside individual fins or the entire radiator. This excess air can then cause cold spots to appear on some parts of the radiator and lower its efficiency and heating capabilities. Ideally you should bleed your radiators on a regular basis as it only takes about 2 minutes max. So just two minutes of your time could lead to cheaper energy bills and a warmer home!

We’ve compiled a handy step by step guide to bleeding you radiators so anyone can follow it.

Step 1: Turn the heating on

Turn your central heating system on. Make sure all of your radiators are on and you can leave it on until it gets piping hot in order to build up the pressure as much as possible.

Step 2: Identify which radiators need bleeding

Once your heating has been on for a while go and check each one individually. Be very careful during this step as radiators can get extremely hot and you don’t want to burn yourself. Check and see if all parts of the radiator are warming up properly, make sure you check all parts of the radiator with a particular emphasis on top parts of the radiator.

Step 3: Prepare

Now that you’ve identified which radiators need to be bled it’s time to prepare. Turn your heating off first, this is important as you don’t want to scald your hands or spill water everywhere. Next, put down some towels. To bleed your radiator you will need either a radiator key or depending on your valve type a flathead screwdriver. If your valve requires a radiator key you can pick one up from your local DIY store.

Step 4: The Bleed

Use your radiator key or screwdriver to open the bleed valve. On most radiators this will look something like the image below. When you open the valve you will hear a hissing sound as the trapped air is released. This hissing noise will finish and you may get a discharge of water from your radiator, this means you can close the valve.

And just like that you have bled your radiator. Repeat on any units in your house that you think may be faulty. There you go minimum fuss and minimal mess and just like that your heating system will run more efficiently. Saving you some money in the process!
