How to Use Radiator Keys

Introduction

Radiator keys are essential tools used to release trapped air from domestic radiators. This guide will help beginners understand how to use the radiator keys effectively to ensure optimal radiator performance.

Tools Required

• 2-in-Pack Radiator Keys
• Cloth or small container (to catch any water)

Step-by-Step Instructions

Step 1: Locate the Bleed Screw

• Identify the bleed screw on your radiator. It is usually located at the top corner of the radiator.
• Ensure your heating system is turned off and the radiator is cool to the touch.

Step 2: Insert the Radiator Key

• Take one of the square opening radiator keys from the pack.
• Insert the key into the bleed screw opening, ensuring it fits securely.

Step 3: Release Trapped Air

• Turn the key slowly counterclockwise to open the bleed valve.
• Hold a cloth or small container under the valve to catch any drips.
• Listen for a hissing sound as the air is released.
• Once water begins to flow steadily, re-tighten the valve by turning the key clockwise.

Step 4: Check Radiator Performance

• Turn your heating system back on.
• Check the radiator to ensure it is heating evenly.
• Repeat the process if necessary for other radiators in your home.

Safety Tips

• Always ensure the radiator is cool before bleeding.
• Use a cloth to protect your hands from any hot water.
• Keep the radiator key in a safe place for future use.
