Electrical is not a big deal just 110volt and low amps. You prob. need 3/4, in most cases a dedicated gas line from the meter is the norm. If its a long run of gas pipe you might need 1 inch. I cant think of 1 tankless install that didn't need a dedicated gas line from the meter and not just branched out from a 1 inch main line running from the house. As far as energy savings, there good but you'll never get your money back from the future maintenance and expsensive breakdowns. depends on the tankless your using,, use to use takagi, and they usually burn at a rate of 199999 btu.
