I want an extractor fan installed in the bathroom and I would like it humidity controlled.
So I can get a cheap fan like this http://www.tlc-direct.co.uk/Products/ADAUE100HT.html or a more expensive one like this http://www.amazon.co.uk/Xpelair-Bathroom-Centrifugal-Extractor-Humidistat/dp/B004TQ0POC or you can go the whole hog and go for a heat recovery model like this http://www.amazon.co.uk/Kair-Heat-Recovery-Extractor-Fan/dp/B004VW3RGW which is significantly more expensive.
So is it worth paying more and what are the real points which I should look out for when choosing a fan for the bathroom ?
Also, what level of humidity should I aim for ? Some go down to 60% and others 40% ?
