Hi nickso
Don't worry, as the original poster I can assure you that the CF boiler does have the required ventilation and has operated perfectly well for years (there were no dead bodies on the floor when we moved in anyway :wink: ). The bungalow originally belonged to my parents.

Hi Agile
'Down' the chimney!
Now there's an idea :shock: but not one I'll be following up :lol:
Guess I'll just have to accept some ugly old white pipe sticking through the roof (no outside wall available). My, the management will be pleased...!
Thanks for your input guys
Hi again baxpoti
Ho, well, I guess that if 'A room sealed flue is part of a gas appliance' then it is indeed case closed m'lud.
Of course, if one could get longer lengths of concentric flue pipe then they wouldn't need joining and there would be no need for inspection access.
I hadn't...
Hi kevplumb & thanks for the interest
Boiler descision is not in stone yet, but it's possibly a Glow-worm 18Hxi.
There would be a couple of 45 degree angles to get the flue from the top of the boiler into the stack, but the estimated vertical flue length within the stack would be 3.5 metres...
Hi, and thanks baxpoti
Possibly NOT case closed :?:
I wasn't suggesting that the seal between the flue pipe and chimney could not be inspected, but the seals/joints between the different sections of the concentric flue pipe.
The flue pipe is made from 2 metre lengths butt-joined...
We've just moved into an aged bungalow and the existing open-vented CH boiler (a floor standing Potterton Kingfisher) is on it's last legs. The existing CH boiler is flued into it's own chimney stack.
The replacement boiler will be a wall-mounted condensing boiler and it seems sensible to me...
