Where to start?
There are 2 types of heating system: sealed and open. Sealed systems can be identified as they have a pressure gauge on the boiler. Open systems have a feed and expansion water tank in the loft. There are normally 2 water tanks: one large one and one small one. It is important to know which system you have before bleeding your radiators as the process for each is slightly different.
TOP TIPS
- Use an old rag or paper towel when bleeding air, as a small amount of dirty water may appear
- Put a small towel or cloth on the floor below the radiator to catch any drips you miss
- You do not need to remove the bleed vent, just open it as much as needed so it can be closed quickly when water appears
- If your boiler has a water pressure indicator, you may need to top up the water pressure during and after the bleeding process
- Boilers with a water pressure gauge have a visible red pointer showing the cold water pressure set point
- If you are unsure of what to do or if there is an problem with your heating system then contact a heating engineer who will be able to help
