Extractor fans bathroom

[ajsdoc]

Was thinking I'd like extractor fans in my bathrooms (they get steamy). Both are recently done (we've only moved recently and bathrooms modern and done before we moved in) so not keen for much destruction or redecorating.

Both have the loft above and are situated on an outside wall.

Is it possible to take an extractor through the ceiling and out at the roofline, and would wiring generally be easy from a lighting circuit?

Another question -electrician or plumber? (I'm assuming electrician). Would the vent to outside if fitted at roof level be fitted from the outside or would the fitter need to work externally? (I ask as I know there are rules and regs about working from ladders and the costs of scaffolding would mean I'd leave this job I think)

Lots of questions just trying to work out if it's a ballache of a job to retrofit to a bathroom (obviously I'd have them fitted when I redo the bathroom one day but wondering whether it could be done now without too much mess?)

All help appreciated.

You could take the extractor vents through the ceiling and out the soffit, through the roof (though you will a trap fitted in the pipe to catch condensation) or through the wall.

They should be wired from a lighting circuit according to manufacturers instructions and can be set to come on with the bathroom light.

Yes there will be mess, but not too much.

Electrician normally because the work will probably be notifiable to the Local Authority Building Control.

The may well be working at height issues but the best bet is to get three quotes before you decide.

It may be possible to core straight through the external wall without too much / any damage, which would be the best soloution.

Failing that, it is perfectly acceptable to fit the fan in to the ceiling, and duct out via the loft, or fit a vent in the bathroom ceiling, anbd then install an inline fan in the loft.

The duct from the fan could either be cored straight through a gable end wall if there is one near by, it could be ducted down to the soffit and out through a vent fitted into the soffit if you can get access to it, or you could get a roofer to fit a roof tile vent, and duct straight out of that.

It is usual for the fan to be supplied from the lighting circuit so it comes on when the light is switched on, and will continue to run for 15 mins or so after the light is switched off.

It is definately a job for an electrician.

As for access, it's hard to say with out seeig the job, but I do most of the work from inside, and then the fitting of the external vent is not much of a job, and I'm quite happy to do that off ladders.
