I have it on 110V 15A branch circuit. That was part of the issue; I hadn't
done my homework, and by the time I went to look at tankless, I didn't
have big enough wiring in place and the walls were mostly closed up.
At the time, I wasn't able to find such small ones. I could have put in
the 240/20A unit, but I could only find 40-60A ones!

Very true. Not an issue for me, but ...
