    Worcester 240 vertex flue

    Anyone know where I can find so install manuals for a vertex flue on an old Worcester 240 combi. I popped into to look at one with no heating (pretty sure it’s a controls issue) but wanted to get some info on the flue before I attempt to fix it. Never actually seen one in the flesh.

    Hello, My mum has a Worcester Greenstar HE30 boiler (15+ years old). Since its last service (and possibly coincidentally) it has been making a booming/banging sound randomly. This is a noise like a pocket of gas igniting and can be loud enough to make you jump. It's been impossible for the...
