Hi guys, Just moved house and it has a back boiler fitted. The fire is a glow worm co-ordiante G (cant find any info on the boiler). Anyway, when i light the boiler it stays on for only ten minutes before going out. The water tank is in a bedroom and there is an emersion heater below it, this has a power switch next to it (but emersion is seperate from backboiler, right?) Anyway i just wonder if anyone has any idea on what the problem could be.
