Common boiler problems

Your annual combi boiler service could also identify some of the most common problems. When they are corrected early, it will extend the life of your boiler.

1. Automatic air vent – If this is fault, you may notice dripping or lime scale at the vent outside.
2. Lime scale build-up – This build up in central heating pipes is common in hard-water areas. It can cause fluctuations in temperature of your hot water taps.
3. Blocked pressure relief valve – A failed or blocked vale can result in constant dripping from the copper pipe on your outside wall.
4. Pump failure – Often caused by sludge, this will stop the whole system from working.
5. Diverter valve – When this valve fails, the system will become ‘stuck’ on either hot water or central heating. Turning on the hot taps might make your radiators heat up too!
6. Sludge – If your radiators are hot at the top and cold at the bottom it may be time for a Power Flush!
