Electric controlled natural gas tankless won't
work during power cuts. When ice storm 2003 hit,
I was out of power, four days. A hot shower
(old style tanked natural gas WH) sure made
life more comfortable.

Whole-house tankless would also have required extending gas piping and new 220V wiring. I'm not a big fan of running 220V when there is an alternative. Plus this house has a 50 year old breaker box & wiring which would have required upgrading.



I don't see why a gas tankless would need 220V. Nothing there that should
require 220. What does it have? Some electronics, an ignitor, maybe a
draft inducer blower?

But the rest of your experience is consistent with what we've heard
here before. I think for the right application, tankless can make
sense, but it usually doesn't make sense for a replacement of an
existing gas tank unit. And if it's going into new construction, that can greatly reduce the cost of the install.
