If it's not run on 110 then I don't see it being much more efficient vs other electric water heaters. Also the idea that it will be easier to install is a farce, it will be the same as any other electric tankless. They're the ones who hyped this up, hope they can live up to it. And you don't have to believe what I do, if you're ever in Minnesota I'll invite you to our shop and prove it to you, how's that?
