    I seem to be going round in circles - I have a 100mm pipe installed under the slab for the air supply to the wood burning stove due to be installed in our new build in the Autumn. Fine so far ....

    But - I'm struggling to come up with a suitable air inlet tower to fit to the outside end. I had originally thought of the Rehau Awadukt (sounds like it's something from IKEA!) product but they start at 200mm dia and it will be rather OTT for a domestic situation. Any suggestions? If I end up having to build some sort of housing for a piece of 100mm drainpipe 1m high, do you think I could fit an air admittance valve on it to restrict air movement when the fire isn't working? Just a thought!!

    Thanks, Jonathan

    What about a 90 degree bend then a very short length of pipe with a mushroom vent on top? What would happen if the AAV packed up, fire go out or CO produced?

    I have an external air supply on a wood stove and the pipe through the wall is standard 110mm drain pipe. I fitted it with a 90 deg. bend turned downwards (as rain ingress prevention) I then put a 110mm to 150mm fitting with an insect screen over the end. I expanded to 150mm to take some account of the air resistance of a (dirty) insect screen. It works OK. (There is enough ground clearance outside to cope with the fittings)

    I am not sure if an AAV would work as a chimney would have a natural draft without a fire lit and if the AAV was strong enough to prevent this natural draft then would this give too much resistance when lighting the fire or indeed when running the fire.

    If an AAV does work can someone please say so and define type and model 'cos I want one as well!!

    That is excellent Owlman - but - my pipe comes out below slab / ground level so I was looking for something vertical that was reasonable to look at so the inlet was around 1m above ground level (we sometimes get heavy snow falls!). The bull nose vent on top would be fine - just got to get that high first!

    Just scanning i-sells again, they have stainless steel flue pipes. the 127 dia x 1m long with a reducer onto our 100mm drain pipe and a decent flue terminal looks a good option!

    Nice idea Triassic - just too far down the road. Can't get to all the bits without some serious dismantling!

    If you got the money you could go for something like this:-

    http://www.prices4antiques.com/nautical/ship-furnishings/Ship-Furnishing-Ventilator-Funnel-Brass-39-inch-C200006.html

    or get something similar fabricated out of sheet steel and paint it, could be a nice piece of artwork.

    The main thing I'd be worrying about is stopping stuff (especially rain) finding its way down the vent. It's got no way to get out once its in there, has it?

    Class! While it will be on the east elevation facing the road (so the farmer and the milk lorry driver will see it!), it is out of the way from our point of view, so cheaper the better!!

    Thanks Owlman. The thought of pieces of art in our 1 acre garden is something that will develop + a folly of course! Not that the French fully understand what that means!

    Sounds like you need a few gnomes scattered around, to help their education. :bigsmile:

    Perhaps you need a small drain at the lowest point so it does not fill with water? I like the schiedel system but at what cost?
