Why Do We Need to Bleed a Radiator?

Radiators are mostly made from steel, which is an alloy of iron. Iron reacts very slowly with water to produce hydrogen gas. Your steel radiators are being eroded and changed to iron oxide and hydrogen gas. Hydrogen is a gas so rises to the top of each radiator where it collects and stops the water heating that part. Your radiators’ heat outputs are reduced as hydrogen collects in each one. Eventually the radiator will be full of hydrogen rather than water and will stay totally cold no matter how hot the water is coming from your boiler. People usually refer to the hydrogen as “air” and talk about air collecting in the tops of radiators. You need to bleed the gas out of your radiators in order to restore them to their full heat output again. This should be done at least once and preferably twice a year.

How to Bleed a Radiator?

Bleeding a radiator is a simple job that anyone can do. You should check all your radiators at the same time, but usually you will find that the hydrogen/air collects mostly in one radiator. Buy a radiator bleeding key from any DIY store; this will usually be about £1. Turn your heating and boiler off and let the system cool down before you start bleeding any radiators. You will need an old tea towel and a damp cloth as well as your radiator key. Do NOT smoke or use any naked flame while bleeding your radiators because hydrogen/air mixtures are explosive.

More on Bleeding A Radiator

Every radiator has a recessed bleed valve along the top that fits the radiator key. You need to turn the bleed valve slightly anticlockwise with the key. Start at the highest bleed valve in the house and work down. As you turn the bleed valve you will hear a hissing sound as the gas escapes. After a few seconds water will begin to escape and you can close the valve by turning it clockwise again and move on to the next radiator. Use the damp cloth and tea towel to prevent mess and to wipe up any that do occur.
