Planning a refurb of an en suite and one of the issues is mould around the shower and on the ceiling.
Room is 1.75m wide x 3.3m long x 2.35 high. Along the long wall the ceiling slopes for about half the width of the room taking the height down to 1.8m. No windows.
Currently have a Marley fan through the wall above the toilet to 100mm rigid duct down through eaves to soffit, distance around 3m.
I was thinking of an inline fan above the ceiling to improve the extraction, so my questions are:
1. I would need to use rectangular duct to get down between the sloping ceiling and the roof. Should I go circular from grille to fan, then fan to converter to rectangular, then should I go back to round profile through the eaves, or just continue rectangular duct down to the soffit.
2. Should I position the extract grille above the shower where the moisture is, or in the middle of the room, or at the toilet end of the room to create a flow through the room.
3. Current fan is triggered from the light switch with an overrun timer. I would want to continue with this arrangement. Should I still install a 3 pole isolator switch?
4. Any recommendations on choice of in line fan. Lots of them look very similar but are there features worth looking out for?
