Bleed your radiator Back to top

You should try to bleed your radiator at least once a year. It is not difficult, but there are some things to keep in mind. If your radiator is warm at the bottom and cool at the top, you need to bleed it from the side of the radiator. If it is warm at the top and cooler at the bottom, you should not bleed the radiator and need to contact us.

This video shows you how to bleed a radiator quickly and safely. If you do not feel confident doing this, please seek further help and advice. If you are a LiveWest customer, feel free to get in touch with us. 

To bleed your radiator

  • You need a bleed key which you can pick up at any local hardware store, and a piece of tissue or towel

  • Put the tissue underneath the valve, insert the radiator key and open the valve.

  • Once the air has purged from the radiator, you will then start to see water coming out of the valve, tissue to catch it and then turn the valve back off

  • Once you have bled your radiators, and if you have a combination boiler, you will need to re-pressurise the boiler accordingly.

If you have followed the above steps and you still have a problem, please contact us.    


Can you see 'communication fault' flashing on your thermostat controller? Back to top

First of all check to see if your boiler is running. 

This type of issue can be caused by low battery power on your radio thermostat, which controls your boiler. This can be resolved by replacing the battery in your thermostat.
