Ice

I have a ceiling extractor fan in my attic for my bathroom shower . This is fastened to one of the beams in the attic. I have two short flexy hoses one from the ceiling grid to the fan and one which couple to a 4" pipe which runs from the fan to the side of the bungalow This then drops via a "S" bend to the outside which has a plastic cat flap on the outside. Luckily enough there is a small piece of plastic cut out at the bottom of the flap frame. I had a shower last night and the condensation created after I had switched the fan off drained through the small gap and now I have a lump of ice on the side of the bungalow

That's because it's cowd

Bung a low roof on it!

well, at least you know that the fan is doing it's job!

Tuddy It soon gets rid of the steam in the bathroom and the room is kept dry .I leave it running after I have had a shower for a couple of minutes so no build up of condensation

I used to love the Massey ferguson but since Jeremy Clarkson bought one, I became an ex tractor fan,,,,,,,

Tom I thought is was because you could not get into Top Gear

Tom, Jeremy clarkson bought a Lamborghini like my neighbour!

Sheeeze, your pandenicness is explained by Peter above, I don't follow Jeramy bloody Clarkson but, I knew he bought a tractor
