How do I know when to bleed my central heating system?
Is your room taking longer to heat than normal? If so, check the following:
- Feel your radiators. Are there cold patches? If it’s cold at the top, there’s air in the system. If your radiator’s cold at the bottom, you may have a build-up of sludge. This is slightly more complicated and might involve an engineer call out.
- Listen to your radiators. Is your radiator making gurgling or clanking noises? These are signs of air trapped in the system, which bleeding should fix.
- Look for damp patches, condensation and mould. These can be caused by uneven heating –radiators that need bleeding might be the culprit.
