Hi, I have an in line shower fan to install and would like to know if it is permissible to exhaust the fan into a convenient disused flue via a piece of 4 inch pipe set in the chimney breast in the loft. The flue is topped with a chimney pot at the moment and will never be used for combustion.
Shower fan exhaust into chimney?

probabaly not since it will be steam, why not vent through the wall or as i did, out through the sofit
There is no soffit, the facia board is flush with the wall. I could bring it out behind the gutter but the chimney route would be a shorter straighter duct if it is allowed. I would imagine that being warm the vapour would rise quickly out of the flue and any condensation would have time to dry out between showers much as rainwater does in a flue or on any exposed brickwork.

I wouldn't.
preumably you shower every day, but it doesnt rain everyday and it never rains steam and warm water

I can get a duct to the facia of the main roof but it will have to have an additional 180 degree bend in it and be twice as long as going into the chimney, which is adjacent to the shower. My big mistake was not putting a flat duct in when I had the ceiling out of the rear addition and was putting Celotex insulation in.

I have seen it done elsewhere but I have reservations about doing it myself, which is why I asked on here.
It does rain most days in Bristol btw
