        I have an 8 yr old AO Smith 40 gal gas hw htr. I originally had a 40 gal electric hw htr. This replacement was supposed to be cheaper than the electric unit and we were supposed to have more readily available hot water. It’s NEVER been that way. Now gas is more expensive and this unit is old and we seem to get less hot water. (already cranked upt thermostat). I’d like to replace it with a high efficiency gas unit. None of the tank types I’ve found have the efficiency of the electric units. However, the tank-types with electronic pilot seem to be just as efficient as the electrics. Questions:
        1). Is there a very high efficiency gas tank-type available?
        2). What are pros/cons of going to a whole-house gas tank-less unit versus gas tank-type?
        3). I know this is the gas forum, but does anyone know anything about the Marathon electric wtr htr (by Rheem, I think ). http://www.marathonheaters.com/index.html If I go electric, that looks like the most efficient and longest lasting of what’s available.

        TIA for your responses, a WONDERFUL site!
