Hello Norfolk Broad - can I ask which fan you ended up installing, and if you are happy with it now that it's a few months on? We are looking to replace our axial fan with an in-line fan and have been considering the Tornado Turbo Tube that you mentioned. Thanks so much.
One of our Honeywell TRV heads broke (like one in photo) and I'm looking for a replacement. These appear to be very old as I can't find an exact match! Will any of Honeywell's current heads be compatible? Thank you!
