On my list of things to do, is to mount a large fan into a spare loft

Already tried it. It made next to no difference.



What sort of size & power fan did you try this with, out of interest -
and is the loft reasonable well ventilated?

Found a formula for the fan size (in imperial)

[ floor area (sq ft) x room hgt (ft) ] x 30 = cu ft per min
required from fan(s)
