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.
When to Bleed a Radiator
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.
Tools You'll Need
Radiator key or a flat-blade screwdriver
A cloth or towel
A small bowl or container
Step-by-Step Guide
Turn Off the Heating: Ensure your heating system is off and the radiator is cool to the touch.
Prepare the Area: Place a cloth or towel under the radiator valve to catch any drips. Have a small bowl or container ready.
Locate the Bleed Valve: This is usually found at the top corner of the radiator.
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.
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.
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.
Turn On the Heating: Finally, turn your heating back on and check that the radiators are heating up evenly.
Important Points to Note:
Safety First: Always make sure the radiator is cool before you start the bleeding process.
