I need to improve the ventilation in the bathroom so have decided to go with a ceiling vent and inline fan, venting to the soffit.
Some thing this:

I've read I need to angle the ducting downwards towards the soffit so any condensation will run out, also not to screw the fan to the ceiling joists as this will vibrate and make noise through the ceiling.

I can't find any information on the best layout for fan and ducting so plan on going for something like the drawing below with the inline fan in position 1 or 2.

Has anyone got any advice on the correct position or any other information that would help?

Cheers

Mine is in position 2 attached to one of the props*

This may or may not be a prop, but its a smaller angled bit of wood. Not one of the main joists.

Only thing I sometimes get is cold drips coming back down into the shower, so guess my up length might be too long. On the plus side my ceiling insulation must be doing a good job :)


Also I upgraded my inline to the highest flow with low noise that I could find (Manrose MF100S). Made a huge difference.

I just did this but as the bricks for the wall go right into the eves, it was impossible to fit a pipe through the 1 inch gap.

After a lot of faffing I decided that removing a brick would be more dangerous (there's a conservatory below) and instead I decided to put a hole through the end wall above the bathroom.

My pipe leaves the top of the vent and my fan is connected to a telescopic pipe. The telescopic pipe is at a downward angle with the inner pipe at the top.. so condensation can run down and out without dropping down into the wall cavity. I've also sealed the pipes together and at the exit point. My exhaust has a down ward vent with a gauss to stop anything making a nest.

So in short my fan is at point 2. Supported by the block wall itself. It's as quiet as it's ever been (I had it sat on the beam before. However an electrician indicated the best spot is 1.. I assume so the condensation doesn't stick to the fan.. The main thing was to keep the pipe between the input vent and the fan as short as possible to limit the condensation in that section.. once into the downward section.. it will just run out.

The same electrician also recommended Manrose too. I may change my little fan to a larger manrose at at some point.

I did this, my thread is here: http://forums.overclockers.co.uk/showthread.php?t=18566935&highlight=fan.

Here's an image of the installation in progress (was much tidier than this in the end!):

I mounted the fan on a gardener's kneeling pad.

I used the Manrose MF100T, purchased from Amazon. It's a beast and fairly quiet too. Those integrated ceiling fans are pathetic by comparison!

Was a bit of a tight squeeze to get to the soffits. From the outside:

Nice job Participant.

Thanks for the link too, Jonnie G certainly knows his onions... Convenient that taking a live from the lighting ring isn't notifiable :)

All very useful info that's helped massively in me trying to get round to fitting one :)

My only stumbling block now though is the fact that the bricks reach my roof tiles and my soffit is 18" below... Ie about 12" below ceiling level. I guess the easier option would be to go through the roof?
 
I thought I'd have that problem so my plan b was to replace a roof tile with a vent that looks like a tile. Presumably a pro job, but a possible solution nonetheless.
