How to Bleed a Radiator: A Step-by-Step Guide by Heywood Heating

Keeping your radiators in top condition is essential for a warm and comfortable home, especially during the colder months. One key maintenance task is bleeding your radiators. At Heywood Heating, West London’s trusted plumbing experts, we believe in empowering our customers with practical knowledge. This guide will walk you through the process of bleeding a radiator, ensuring your heating system operates efficiently and effectively.

Section 1: Signs Your Radiator Needs Bleeding

It’s not always obvious when a radiator needs bleeding. Here are some tell-tale signs:

• Cold Spots: If the top of your radiator is cooler than the bottom, air might be trapped inside.
• Gurgling Sounds: Noisy radiators often indicate air bubbles in the system.
• Inefficient Heating: If your room isn’t warming up as expected, trapped air could be the culprit.
• Remember, regular bleeding can enhance your radiator’s performance and improve your home’s energy efficiency.

Section 2: Tools You’ll Need
Before you start, gather the following tools:

• A radiator key (available at most hardware stores).
• A cloth or small towel to catch any drips.
• A container to catch water if necessary.

Section 3: The Bleeding Process

1. Turn Off Your Heating: Ensure your heating system is off and radiators are cool to the touch.
2. Locate the Bleed Valve: Find the bleed valve, usually located at the top corner of the radiator.
3. Position Your Cloth and Container: Place the cloth under the valve and the container close by to catch any water.
4. Turn the Radiator Key: Insert the radiator key into the valve and slowly turn it anti-clockwise. You should hear a hissing sound as air escapes. NOTE – Be careful not to remove the air vent fully.
5. Wait for Water: Once the hissing stops and a small amount of water leaks out, this indicates that the air has been released.
   Close the Valve: Quickly but carefully close the valve by turning the radiator key clockwise.

Section 4: Finishing Up

• Check Other Radiators: It’s a good idea to check and bleed all radiators in your home.
• If you have a combi boiler or a sealed system (filling loop and pressure gauge), you will need to top up your heating pressure.
• Turn the filling loop on till the pressure displays between 1 – 1.5 bar 
• Turn Your Heating Back On: Once all radiators are bled, turn your heating system back on.
• Monitor for Leaks: After bleeding, keep an eye out for any leaks.
