How To Balance Radiators

Do you have hot and cold spots in your radiators? Hot and cold spots in your radiators mean they need balancing which will ensure an even distribution of heated water to each radiator.

Balancing radiators shouldn’t be confused with bleeding a radiator. Balancing a radiator is the process of ensuring all radiators throughout the home emit, a steady, consistent heat when the central heating is switched on.

Here at Yorkshire Boilers, we’ve created a handy step-by-step guide to show you how to balance radiators…

How To Balance Radiators

If you’ve noticed you have hot and cold spots in some of your radiators or found that some radiators get warm whilst others are cold in your home, then your radiators need balancing.

Follow Yorkshire Boilers simple step-by-step guide on how to balance radiators.

What Tools Do You Need To Balance Radiators?

You need the following tools to balance your radiators:

  • Radiator bleeding key
  • Screwdriver
  • Lockshield value adjuster or adjustable spanner
  • Digital thermometer
  • Pen and paper

Step-By-Step Guide On How To Balance Radiators

  1. Firstly, you need to make sure all the radiators have been bled. Then turn off the central heating and wait for the radiators to cool.
  2. Next you need to find and familiarise yourself with the valves on your radiators. You will have a lockshield valve at the bottom end of your radiator it will usually have a push-on cap, or a secured cap with a screw through the top of it. You need to remove the cap of the valve all together.
  3. Once you have removed the cap of the valve you need to open all of these valves fully by turning them anticlockwise. You also need to open the thermostatic radiator valve by turning them anticlockwise.
  4.  Turn the central heating back on, grab a pen and paper and note down the order the radiators heat up. It’s likely the radiators closest to the boiler will heat up first. Doing this will give you an idea of the order in where the hot water reaches each radiator.
  5. Switch the central heating off an wait for the system to cool again
  6. When the system has cooled turn the heating back on and go to the radiator on your list which heated up first.
  7. Turn lockshield on the radiator clockwise until it is close, then turn it by a quarter to open it. When the radiator is warm, use the digital thermometer to take a temperature reading at the pipework leading to one of the valves.
  8. Afterwards take another temperature reading at the pipework leading to the other valve. Then gradually open the lockshield valve until there is a difference of 12 degrees Celsius between this temperature and the last temperature you took.
  9.  Finally, go round and check the rest of the radiators following the order of the list you wrote. You usually find the further away from the boiler you are, the more the lockshield valve will have to be opened. The last radiator you check may need to have the lockshield valve fully open to work at full efficiency.
  10. When all the radiators have been checked they are now balanced and should work perfectly. However, if you are still experiencing hot and cold spots in your radiators please call one of our heating experts on 0808 156 7704
