Bathroom fan in loft space - ducting length

by declanmullan » Wed Aug 30, 2023 10:59 pm

Hi all,

We need a more powerful fan in our bathroom as we've been getting a lot of condensation and mould. I want one of the inline fans where the motor will be in the loft above the bathroom.

But we intend to do a loft conversion in the future, so wondering how long the ducting can be on these, so that we can have some flexibility in where exactly the unit in placed in the loft when we come to do the loft conversion.

How long can the ducting be? Any other considerations or options I should be aware of?
