Please note: Our ‘How-To’ manuals are intended only as a guide to assist you with common home heating tasks. Please do not attempt to undertake this task if any of the instructions are unclear, or if you are in any doubt about what to do. Instead, seek advice from a professional.

What You Will Need:

  • Radiator bleeding key
  • Lockshield valve adjuster or adjustable spanner
  • Screwdriver
  • Digital thermometer or multimeter with that function

Make sure all the radiators have been bled. Turn off the central heating and let the radiators cool down, until they are cold.

Find the lockshield valve. It will have a push-on cap, or a cap that is secured with a screw through the top of it.

Open up the valves on every radiator in the house by turning them anti-clockwise. The lockshield valve will need a plastic adjuster or a spanner to open it.

Turn the central heating on and take note

of the order in which the radiators heat up. Radiators nearest the boiler will often get hot first.

Turn the heating off and wait for the radiators to cool down.

When the radiators are cool, turn the heating back on and go to the radiator on your list which heated up first.

Turn the lockshield valve clockwise until it is closed and then open it again by quarter of a turn.

When the radiator is warmed up, take a temperature reading at the pipework leading to one of the valves.

Next, take a temperature reading at the pipework which leads to the other valve and gradually open the lockshield valve, until there is a 12°c difference between that, and the temperature reading from the previous step.

Now, check the rest of the radiators in the order on the list. Generally, the further the radiator is from the boiler, the more the lockshield valve will have to be opened.

The radiators are now balanced and should be in great working order.
