Small Shower Room Ventilation.

I was talking to a developer this morning. His son is a sparks. The two have installed a new 4 inch ceiling fan in a small upstairs shower room that has no windows. The building roof has been renewed recently and new breathable "felt" installed under the tiles. I had previously mentioned that the roofers could install a new roof vent for the fan ducting, but nothing has been done about this.


The developer says that the son advises terminating the air duct in the loft onto a bucket to catch moisture, which I said was not acceptable.


Bearing in mind that the new roofing "felt" (membrane) is breathable, is there any reason these days not to terminate the air duct directly into the loft space with no external grille?

    The heat pump is not more than the tumble drier with an internal dehumidifier, eh Chris?

    Not quite. These driers still condense, but instead of heating the air using resistive elements, they do so with a heat pump. The consequence (as I understand it from reviews) is that the drying cycle takes longer, presumably because the drying air is not as hot.
