How to Bleed a Radiator: A Simple Guide for Tenants

If you've noticed that your radiator isn't heating up evenly, with cold spots at the top and hot at the bottom, it's likely that air has become trapped inside. This is a common issue that can usually be resolved by bleeding the radiator. Here's how to do it and when it might be necessary.

• Cold Spots: If the top of the radiator is cold while the bottom is hot.

• Inefficient Heating: If the heating system seems less effective than usual.

• Noisy Radiator: If you hear clanging or gurgling noises from the radiator.

• Radiator key or a flat-blade screwdriver

• A cloth or towel

• A small bowl or container

1. Turn Off the Heating: Ensure your heating system is off and the radiator is cool to the touch.

2. Prepare the Area: Place a cloth or towel under the radiator valve to catch any drips. Have a small bowl or container ready.

3. Locate the Bleed Valve: This is usually found at the top corner of the radiator.

4. Open the Valve: Insert the radiator key or screwdriver into the bleed valve and turn it counterclockwise. You'll hear a hissing sound as the air escapes.

5. Close the Valve: Once water starts to leak out, this indicates that all the air has been released. Close the valve by turning it clockwise.

6. Check Pressure: After bleeding all the radiators, check the pressure on your boiler. If it's too low, you may need to top it up.

7. Turn On the Heating: Finally, turn your heating back on and check that the radiators are heating up evenly.

• Safety First: Always make sure the radiator is cool before you start the bleeding process.
