Bathroom Extractor Fan opinion...

[Des 56]

Do you mean MVHR Des? If so it does work a treat, but no loft access available for the landlord in this case. If you mean something else what is it please as am curious..

I presumed there was a attic after reading his comment below,I did have a dry air unit in mind which would be mounted in the attic
I have fitted many of these units over the years and have had good feedback in all cases

quote(Not aware of trades accessing the loft space but the council's contractors are inspected the roof at the end of the month).

If he has no attic there is a unit designed by the company I use for the fans specific for flats but I have never installed one myself

In my experience (as a landlord) this seems likely to be a tenant-specific problem, drying clothes with insufficient ventilation etc. If you do fit a good quality extractor fan, that comes on automatically, the isolator needs to be locked as they will switch it off. I had one tenant who decided that he was not going to allow the fan to run on for 10 minutes, and as the isolator was locked, he simply unscrewed the fan housing and reset the timer to zero run-on...
The place was full of mould in 2 months.
My opinion is just wait til council inspection is over, then install in loft space...if it's truly communal. so what? The intrusion of a flange and some ducting is minimal, and probably will go un-noticed anyway. If the tenant is unhappy due to cost of electricity...get Big Pete in, to "explain" things clearly...

^^ my guess is that the OP will need access to the roof space to run the cables .............
