Best trick for energy efficiency – Bleed the radiators!

DIY radiator bleeding – best solution for energy efficiency

Nearly 84% of UK households use gas heating systems for warming up their homes. There are often times when your heating system is not performing up to its optimum level. The main reason of poor performance is the presence of air bubbles trapped in the radiator. These bubbles act as road blocks for water circulation in the system and thus prevent proper heating. These bubbles need to be removed and the process is called radiator bleeding.

You can also bleed a radiator on your own. The process is simple and needs no special training or qualification. All you have to do is the following.

Steps to follow to bleed a radiator:

  • First of all, switch off the central heating system. This is to prevent boiling water from spreading out of the radiator.

  • Keep the tea towel, radiator key and bowl for collecting water next to you. Do not use pliers instead of the radiator key as the pliers may damage the body of the radiator. It is always advisable to use the key.

  • Locate the bleed screw. You will find it at the top corner of the radiator. Now, place the bowl to collect water underneath the base of the radiator.

  • Place the radiator key onto the bleed screw in such a way that it fits snugly. You can put a piece of cloth over it and then rotate for about half turn in an anti-clockwise direction. This will release air with a hissing sound.

  • As soon as the air gets released, water will start dripping down slowly into the bowl. That’s it! Your job is done and the air bubbles are released. Now, tighten screw carefully. This is to prevent any damage to the valve.

  • As a good practice to prevent rusting, just wipe the radiator with a cloth to prevent moisture. Now, switch on the heating system and check the pressure of the boiler. Check all radiators to make sure that there is no leakage in any of the bleed valves.

  • If you find that the DIY job is not giving you a 100% result then call up a heating engineer to get things resolved.
