: I am extremely cramped for space in a small house and am looking into tankless hot water options. My
: best bet for squeezing a stacked washer/dryer into my house is where the existing hot water tank is, but
: then the hot water has to move. Tankless seems perfect as the house is very small and I live alone, but
: I've yet to find anyone with much experience with these things. I know these are popular in Europe, why
: not here? Don't know if it matters, but I'll need a gas unit.

: I'd also be interested in hearing any ideas about alternative hot water tank configurations/placements
: (i.e., such as a crawlspace). Thanks!

I have installed three of these.
All working well.
Note that you have to supply combustion air to the unit.

Initial cost puts a lot of folks off, but long-term are the way to go.

For tank-type water heaters there are some fairly short low-boys that
could go in a fairly short crawlspace if it is dry and
you can dig a bit of a pit to set it in.

Good health, Weogo
