Using 2 units

[thomas]

What's the best way to use 2 smaller units for a single dwelling?

Is it best in series, parrell or separate zones with equal wet dry zones? Or something completely different.

You wouldn't use then in series, but parallel.  How you parallel is different you could combine the two with a' series of Y' type branches (my original plan), alternatively separate the zones, that is what I did, downstairs and upstairs, down I have Kitchen, en-suite, WC and laundry, upstairs I have 4 bathrooms/en-suites and an AC.

Very good blog!

Did you have 2 separate sets of external intakes and exhausts?

I suppose the main disadvantage of having 2 units is you have to mount the horizontally so take up a lot more space ?

[le-cerveau]

Yes, 2 x intakes and 2 x exhausts.  However They are 180mm and that is the largest practical tile vent.  If I had one unit (light commercial) I would have required 250mm intake and exhausts and that is problematic!

 

Yes 2 units take up space but If I had gone for a light commercial that would have been much larger and with its own issues of mounting.  I have a plant room and even that is running out of space, whatever you think you need double it as you always need more space and things don't fit quite as you planned!
