How to bleed a radiator
If you notice your radiator(s) are not heating up correctly there may be air in the central heating system, this is usually an indication that the radiator(s) need ‘bleeding’. This is a simple job, to help you complete this with confidence we have attached the following video. Please note we advise you to turn the heating off and give the system time to cool down before bleeding the radiators to avoid any risk of scalding. After completing this task you may need to repressure your boiler, for help with this see the ‘how to top up your boiler pressure’ video further down this page.
