Had one in my flat in lieu of a proper kitchen extractor. Ended up just running wiring it to run on boost only, rather than the permanent low run as it didn't seem to recover that much heat and was a bit noisy. Seemed quite agriculture for the cost when I opened it up. They require a drain point for condensation. I think mine was a vent axia.
Started thinking about it again recently, I reckon an unused chimney would be a good route for the clean air in, pumping it in at ground floor and extracting humid air on the top floor to go with the natural route of warm, humid air. Probably a hassle to install though.
i've read that there is a pretty quality (and results) huge gap in low end to high end, particularly around the quality of materials and forethought of installation layout, etc
I'm sure, for that scenario I wouldn't choose to go that route again, but for a whole house I could see it making sense if you can figure out a way of getting the installation right.
