We fitted one of these some years ago and it made a huge difference to damp in the house and made the house feel warmer. It had to come out when we had a loft conversion (which seems to have been equally helpful for damp etc). That was in a '30s semi with cavity wall insulation, double glazing and no trickle vents.
