Bleeding a radiator is a simple yet essential maintenance task that can make a big difference in the efficiency of your home heating system. Whether you have a radiator key or not, this article will guide you through the process step by step to ensure your home stays warm and cosy during those chilly British winters. This tutorial is also suitable if you’ve recently removed a radiator for decorating but are now putting it back. Bleeding is an essential step to get it working normally again.
TOOLS REQUIRED
Tools
- A radiator key (readily available at DIY stores) OR pliers/ adjustable spanner
- A cloth or towel
- A small container to catch any water
STEP 1: TURN OFF THE HEATING
Switch off your central heating system. It’s better to work on a cool radiator to avoid burns.
STEP 2: FIND THE BLEED VALVE
Identify the bleed valve on your radiator. It’s typically a small square or hexagonal nut located at the top of the radiator, often on the side.
STEP 3: POSITION THE TOOLS
If you have a radiator key
Insert the radiator key into the bleed valve. Make sure it fits snugly.
If you are using pliers or a spanner
Grip the bleed valve gently with the pliers or spanner.
STEP 4: OPEN THE VALVE
Slowly turn the radiator key (or pliers/ spanner) counterclockwise (left) by about a quarter to half a turn. You’ll hear a hissing sound as air escapes. Be ready to catch any water that may dribble out.
STEP 5: CLOSE THE VALVE
Once you see a steady stream of water, close the valve by gently turning the key, spanner or pliers clockwise (right). Do not overtighten.
STEP 6: CHECK FOR LEAKS
Wipe away any excess water, and ensure the valve is properly closed. Turn your heating system back on, and check the radiator for warmth. You should notice improved heating efficiency.
CONCLUSION
Bleeding a radiator is a straightforward process that can enhance the efficiency of your heating system. Whether you have a radiator key or not, regular maintenance like this can keep your home warm and comfortable throughout the British winter. Remember to check your radiators periodically and bleed them as needed to maintain optimal heating performance. Stay warm!
