Bleeding a radiator is a simple process anyone can do at home. It’s important to bleed your radiator to make sure your heating system works effectively, especially during the winter months. Follow these step-by-step instructions to do it yourself.

What You Need

  1. Radiator key or a flat-blade screwdriver
  2. A cloth or small towel to catch any dripping water
  3. A small bowl if needed

Steps to Bleed a Radiator

  1. Turn off Your Heating: Start by turning off your heating to avoid burning yourself while working with the radiators.

  2. Locate the Bleed Valve: Every radiator has a bleed valve. It’s usually at the top and side of the radiator.

  3. Insert the Radiator Key: If you have a modern radiator, a flat-blade screwdriver is enough. For older radiators, you might need a radiator key. Insert the radiator key or screwdriver into the bleed valve.

  4. Bleed the Radiator: While holding the cloth under the valve to catch drips, slowly turn the radiator key or screwdriver counterclockwise. You should start hearing a hissing sound - this is the trapped air being released.

  5. Close the Valve: Once water starts to leak out, this means all the air has been released. Immediately close the valve by turning it clockwise. Be careful not to over-tighten it as you might damage the valve.

  6. Turn on Your Heating: Now, all the trapped air should be released, and you can turn your heating back on. Check if all your radiators are heating up uniformly.

Remember, consistency is essential while performing radiator bleeding. It’s recommended to bleed your radiators at least once a year, preferably right before winter. With these steps, you can easily and safely perform this routine maintenance task at home.
