We currently have a through the wall fan in the bathroom which is ... "rubbish". Apart from performance and noise (to the point where SWMBO will switch it off before showering), it's at the wrong end of the bathroom - as far from the shower as it's possible to get. I'm thinking of putting an inline fan in the attic and venting through the roof - that way it can suck the moist air from where it's being created. I also have in mind possibly swapping it for a MVHR at some point to supply pre-warmed air to a couple of places that get a bit cold and damp.
Then I thought, there's a couple of disused chimneys. Would it be reasonable to take a few bricks out of the stack in the attic, lower a piece of 150mm duct down, use a 90˚ elbow and some more ducting to come through into the attic - then refit some bricks round it and fit a cowl at the top ? I'll do the inside work myself, but get someone in to go up and do the work on top.
What would be the best sort of cowl to use ?
How best to seal between duct and chimney stack ?
Could I leave the existing (round) pot in place ?
Is 150mm likely to fit ?
It's an ex council house, circa 1940s, brick built. I'll get a photo when I'm home during daylight and it's not peeing down.
