Hi, this might solve your dilemma... A pipe under the floor to the air inlet so your building remains sealed, this was implemented in my design 'crucible' - I design & build made to measure woodburners. regards, Owen

We usually spec an internal slotted/louvered vent for these depending on location. That way you can close the vent when the stove isn't in use and reduce the drafts.

So start to finish, it'd be an air brick on the outside wall, connected to a plastic duct pipe (rectangular or round to suit the conditions) taken under the floor and depending on your fire place you can bring it onto the side wall of the chimney breast, or in front of the hearth etc, then use a louvered grill in a finish to suit your decor.

What you should avoid is having the inlet behind you when you're sitting in front of the stove as this will be drafty on the back of your neck.

If it's a new build then consult with your designer/architect etc to agree the best position.

Many thanks. I was told that B regs stated that you cannot fit a vent or grill that can be closed off ? I realise that what I do after the build is 'signed off' is unlikely to be inspected. An option to be considered though.

PS I build 'direct air' dual/treble & all aspect stoves! See stovedesign
