I did a brief search and couldn’t find a similar situation but that may have been me not using the correct search terms as this isn’t my field.
So in short we are trying to complete a new build 3 storey house for Building Regs Sign Off. The top floor has a bathroom and a Shower Cubicle in one of the bedrooms both of which require extraction. Fans have already been fitted in the ceilings in appropriate locations by the previous builder who has now been kicked off site for being unreliable among other things.
The site on which the house is built is such that the third storey is almost 4 storeys above ground level and surrounded by steeply sloping ground making ladder/cherry picker access either impossible or highly dangerous. All scaffolding has long since left the site. This means accessing the outside of the building will be almost impossible/prohibitively expensive to fit an external vent.
So my question is this is there some kind of a device we could fit inside the loft space which would dehumidify the extracted air from the shower and bathroom so that dry air can be vented into the loft space? If so what is this called?
I have found duct moisture traps during a Google search but based on the limited descriptions and my limited knowledge I assume that these are merely to extract any water which condenses in a duct on the way to being extracted outside?
One other fact which may be pertinent to this there is also a rain water harvesting system in the house and the “brown water” header tank is in the loft space nearby so could be used to receive water from any extract system assuming this wouldn’t contravene the Building Regs of course.
