Hi gucciman, Just read the Alpha ( spit ) post, couldnt have put it better myself well done mate.
You would not normally site a boiler above a hood as ceiling height is an issue as you say, but theoretically you could. There is no regulation to say you couldnt but i agree you would need very high ceilings to comply, And jon1968 only asked for the regs regarding siting the boiler in relation to the hob. Nice to see you are still posting. Now i am back in the country again i shall be a bit more active again myself. keep up the training and good work.
