Hi,
Apologies if this has been covered elsewhere, but I can't seem to find the answer.
Our bathroom has no window, but an old inline fan in the loft which extracts from a vent in center of the room. The fan needs replacing as it's not powerful enough (and it sounds shot). It's just venting to 'near' the eaves. The roof design prevents the ducting from reaching the soffitt without hindrance, so that option is out.
- The extractor has a run on timer which is wired into the pull cord (light and fan come on at the same time)
- We have a roof tile vent to extract to (due to the soffitt problem)
My questions are as follows:
1. Venting to a roof tile means that the ducting will be going up and up, therefore there maybe a risk of condensation running back down the pipe.
- Would you always need a condensate trap for this? If so, where in the line of ducting do you put it?
- Where would the condensate go to?
- The distance from the current bathroom vent to the tile vent is approx 1.5 metres
2. I could move the vent in the bathroom over the shower (source of the moisture). This would mean that from there to the underside of the roof tile vent would be 0.5 metre in a straight line almost.
- Would there be any problems in having a short ducting bend (from bathroom vent) - inline fan - then short ducting to roof tile vent? Again what about condensation running straight back down - would this be a problem in such a short run?
- I would need to extend the cable that powers the fan also.
The roof tile vent has a duct opening of 110mm and most of the ducting is 100mm. are you supposed to use one of these: http://www.aboutroofing.com/shop/buy/Manthorpe_/Flexible_Pipe_110mm_x_455mm/
Any ideas of the best option, course of action I should take, would be appreciated.
Thanks
