| Sumo, I'm not a big fan of tankless, but if you have good water quality and can't resolve the space issues, then go for it. I'm sure if more people had enough space for tanks in Europe they wouldn't have so many tankless. In fact because of the space situation they actually have wall mounted tanks fired by wall mounted boilers (mostly boilers there). That said...
Get a Rinnai or another top name brand. Size the two units to your loads. I'm not sure I would have your contractor install them and I'm not sure how your contractor feels about having someone else come in, but I would have it installed by whoever is going to service it. Service will be important, because if anything happens, the hot water stops right away.
My opinion on your reasons...
#1 - compared to standard wasteful gas-fired tanks - yes
#2 - that gets offset by a narrower min and max flow
#3 - bingo! |
