I've had no end of problems with my bathroom ceiling fan, as the ducting goes straight up through the loft to a vent in the roof, so any condensation on the inside of the duct (which is shitty tumble dryer flexi-duct) just drips back down onto the fan, shorting it out. My second fan has now broken, and condensation drips out of it into the bath.
What's my best bet? Some kind of condensation-trap trickery, or installing a proper rigid duct and lagging the duct through the loft?
