| I used them in Japan too, liked them. The fact they're seen on every apartment and hotel balcony, suggests they *are* efficient. I can't wait to install one of these babies.
I wouldn't choose tankless, though, just because house design forgot utility space. If you're yet at the stage of realizing the puzzle of your home must accommodate these pieces, well... sometimes little problems like this force us to rearrange and sometimes get a better result than before we had a problem.
One thing tanks do have over demand heaters, is waste. When most of your energy bill is heating season, a basement tank "wasting" heat into the room looks like something for nothing next to tankless mounted outdoors.
Another thing tanks offer is integration with hydronic heating. If you'd like to heat your home this way, try adding "combined system" or "combo system" to your Google search.
Hmm. While I'm on the "cons" side of this argument, I'll add that however much geek-appeal tankless heaters have to people like myself, they really do look just like ugly box-things to most folks walking by your lovely home.
