Can a gas boiler flu run externally from ground to second floor?

[ardorban]

does anyone know of a system that will allow a gas boiler (any) with a flu length to reach the ridge line (second story from ground) on the outside of the house, so about 7 or 8m? The boiler can be mounted on the external wall so there is only one bend.

We have an annoying neighbour and so cannot vent onto his land but cannot find a flu system that will allow this?

The wall you'll be flueing out of goes straight into your neighbours land?

If it crosses the boundary outside of guidelines then he can legitimately ask you to move it

Veismann boilers do one see page 20 flue option 5 (can only be used with their boilers)

I’m pretty sure most boiler manufacturers do a concentric fluing system (I think it’s called this) 2 individual flues one for product of combustion and the other for air in take

Intergas do as above or a normal concentric vertical flue up to 10m but you must factor in the fittings a 45 degree bend is equal to 0.5m of a meter and a 90 degree bend is equal to 1m of flue each section must have a bracket adjacent to the joint be accessible for inspection in case of leakage in the years to come and to examine it for its integrity .

Thank you - does this apply to flues on the outside of the building?

Thank you Chris!

I don’t think so but your engineer could check with manufacturers. I have seen it done externally. Alternatively you could get a flue plume kit installed externally.

You still haven't answered Craig's post #2

Well it's a simple yes or no answer. He's obviously not bothered to think why I might have asked that question. Nevermind

The solution is dependant on the answer. Ah well.

No flues need to be internal there would be to much condense coming back down the flue all the manufacturers diagrams show internal .

Except the Veismann, KOP
