Ceiling Extractor Fan

[ziggy1979]

Hi Everyone

This may sound like a really silly question but is it possible to connect the ducting to an o verflow pipe in the loft, for example by using a condensation trap rather than going out the roof or eaves?

The reason for this is that we are really high up and scaffold is needed to put in roof or eaves vents as we were told that these have to be fitted from outside.

I'd be really grateful if there are any other solutions which might help - the extractor fan is for our bathroom.

Thanks a lot

Not sure what you're suggesting here, but I think is sounds like a bad idea. These fans need the most unimpeded airflow you can manage if they're to work efficiently.
Are you talking about 3/4" overflow pipe? If so the scheme is definitely a non-starter.

Nice idea, but limiting the size of the final pipework will slow down the airflow too much - it's not just steam your're trying to remove.

There are alternatives - one of which includes using some rectangular ducting to push down the eaves if there's a suitable opening in the soffit board. This can be connected to the flexi circular ducting with tape directly without the need for a special joint.

Another way would be to remove some of the roof battens adjacent to where you want to install the roof vent, and the tiles with it. You may be able to create enough of an opening (depending on the space between the rafters) to gain access to the roof this way. Depends what sort of roof you have - if tiles rather than slates then, although fiddly, this is feasible.

A final solution would be to bite the bullet and get a roofer (they don't mind heights) and it will probable cost you less than a hundred for him to do the work - it's less than an hour's work, and that includes putting up ladders. Depends just how high up it really is.

Could you not put vent thru wall, external vent can be fitted without going up ladders.
