What is a condensing extractor fan? Engineer recommends use

[badhairday]

Basically, I have condensation issues on the bathroom on the top floor. I have been advised that it's hard to drill a hole in the wall, since the bathroom is on the 3rd floor and they would need a v high ladder. So, they advised I get a condensing extractor fan installed. What is that? Does it work as well as conventional?

Also, I suppose it is possible to drill a hole for the extractor fan from inside the house, instead of getting a ladder and doing it from outside, however, I was wondering what is the best way of avoiding unsightly gaps/holes from the outside? Is there a way I can cover the pipe/hole without getting on a ladder outside the house? Perhaps some kind of shield I could put on the pipe before pushing it through the hole that has been drilled. Know what I mean?

I presume he means a fan with a humidity stat which basically operates when it detects humidity at a certain level which you can set and adjust yourself.

I have one fitted and it seems to work well

Would a fan like this not require to a hole to be drilled then?

I have seen them and they vent out like a tumble dryer with it going out of the wall.

So you can drill a hole from inside the house, and you wont have to get on a ladder for 3 stories to stick an airvent on?

Also, is it a question of sticking an airvent on with sealant or do they have to be drilled into place? If it something that can be slapped on. that makes things a lot easier.

Find a different installer who has the correct access equipment to do the job properly...

Installation instructions (link within the link) show that the unit is a push fit from the inside and a finned seal takes care of weather proofing. There's an external bezel supplied which can be fitted for neatness 'if required' so it appears to be optional.
