You know, I could locate the tank elsewhere, but I'd be putting the unit about 20 feet further from the kitchen and the location of the new master suite. The run from the well pump would also be lengthened about 20 feet. I would have to run the 1" Wirsbo PEX along the rim joist to avoid punching 30 holes round trip in my floor joists. I guess I'd have to run the whole bundle of 1/2" along the rim joist as well. I'm just want to be sure I can supply enough volume for my Kohler River Bath and everything else.
FWIW, my tankless is about 40 feet from our master bath. In comparision between our old tank setup and our tankless, it takes about 8 seconds longer to get hot water now to get to the shower.... No biggy. You won't have a problem filling that 200 gal tub that's for sure!
On another note, it would scare the crap out of me to have pipes to tankless in the attic that could freeze. Talk about a making a mess of the house. But maybe they do that up north and don't think twice.
