Extractor fan cost ?

[rockstarchick]

Help!

So I've moved to a lovely flat
There's one problem
It has no bathroom window and there's an extractor fan - fine so I thought

I moved in 5 days ago and I thought the extractor fan was stuck on ON
The electrician has taken until now to come out as bank holiday and only reported it Friday
Anyway he says this -

It isn't stuck on ON its on because of the humidity
I've said well it never goes off!! Even at night?!
And I cannot sleep as I can hear it through the walls
He says once the humidity goes it will go off but it doesn't

I've turned the fuse off as I couldn't cope with the sound
He says because I have done so that's why it's on constantly
But now I'm not touching the fuse as he says if I do and there's damp I will get the blame

Fair enough anyway so I've bathed and it's ON
He says there is a humidity control which I can turn to low at night but recommends I turn it back up to high when I go out which obviously
I'll do

But I've never had this problem before
But he said as there's no window and it's a large bathroom then I just have to put up with the fan
But the thing is it could come on anytime even though it's turned low at night time

Does all this sound right because surely not ? It's super loud and at night it's keeping me awake

Help me - any electrician advice or people that have bathroom with no window? Surely you can buy good humidifier- not those cheap couple of pounds ones
I wouldnt mind spending money if I knew that fan wouldn't come on at night
It's and enough in the day
I bathed an hour ago and it's still bloody on ?!

Thanks for reading x

please put up a photo of your existing fan

1. If it is noisy, new ones are available with ball-bearing motors which are very quiet, and pretty well inaudible when the door is shut

2. if your existing fan has not been able to reduce the humidity, there is something wrong. Perhaps the duct is faulty; perhaps there is no duct; perhaps you have a hidden water leak making the room wet.

Fill a glass bottle with cold water and take it into the bathroom., Shut the door. Does the glass become wet with condensation?

If you know anybody who smokes, allow them to puff a fag in the bathroom with the door shut. Go back in after five minutes. Is it still smoky? Can you smell smoke in any other part of the flat? (if you are a smoker yourself you will not notice it).

Thanks for your help
I'm still waiting for my letting agency to call back so this is really helpful!

It was on all day when I set the detector to high but when I set it to low it goes off

I'll post a pic when I am home

I don't smoke so can't try that option
