We are looking for a bathroom extractor with humidity sensor with a chrome finish

So far I have only managed to find 1 which was £143 quid

Any ideas where I might be able to get one a bit cheaper ?

Thanks

Is that chrome as in a nice piece of metal with real chrome plating, or as in that nasty plastic stuff used on cheap consumer electronics products?

Seriously, kazzab - if you want a chrome finish to match real chrome or polished SS taps etc don't bother - that shiny plastic always looks C&N - IMO you'd be better off with something white and unobtrusive, e.g. a flush-mounted one of these:

or if layout permits an inline fan in the loft so that all you see is a grille on the ceiling.

I reckon that unless it gets too noisy, or starts pulling the door off its hinges and pinning animals or small children to the wall, the bigger the better for extract fans, don't go for the minimum rate worked out by a calculator.

You can get a chrome effect facia for the Icon fans

But it's expensive.

And is probably still made from that tacky plastic used on cheap consumer electronics products
 
Yup.

That would do about 50 air changes per hour for mine.

I see they do one which would get me 100 per hour :mrgreen:
 
Actually I'm wondering if you can have too much of a good thing.

Doing some rough calculations, if I've got, say a 130 sq cm gap under the bathroom door, and a fan trying to drag 1100m³ per hour through it, doesn't that mean an 84.6km/hour, Force 9, strong gale blowing under the door?
 
What will happen is that as the fan extracts air, the pressure in the room will drop. The lower the room pressure, the less air the fan can extract, so the amount of air extracted drops. To counter that, the lower the pressure in the room, the faster the air flow under the door, so there will be a steady state pressure at which the two balance. The fan won't be pulling anything like its maximum, but the maximum velocity under the door will probably be quite high, since the flow velocity near the edges of the opening is low.
 
When I used to do disabled bathroom conversions for the council, the bathroom door was sucked open a bit when you turned on the extractor fan :D
 
Thanks timbim.

I should have had a ;) in my post - I knew I wouldn't really get a gale blowing under the door, but it was an amusing calculation to do.

And on a serious note I'm probably not about to spend £330-odd on a fan. But I think I will start looking at ones in the 500-800m³/hr bracket.

Yes I've only got a 10m³ bathroom, but by the time I take off losses for ducting, inlet grille, backdraught shutter and the drop in room pressure I don't expect I'd be exceeding the "standard" recommendation of 150-200m³/hr by a stupid amount. Less than double would not surprise me.
