We recommend Ruud & Bradford White water heaters. We feel they are better than the competitors' brands. Generally, these have better insulation, faster recovery, more gallons in the first hour, and brass drain valves (not plastic).

50-gal gas Ruud Professional Series water heater, comes standard with 6 year warranty. This customer added the Extra Anode which provides an additional 4 years of warranty for a total of 10 years worry-free service.
I don't like these using copper flex lines, they are easy to kink. And sweat-on lines are very difficult to remove.
another happy customer! 6-year warranty plus extra anode makes for a total of 10 years of worry free service.
no gas so tankless wasn't an option; installed 75-gallon Marathon with a Recirc pump, now they have lots of hot water on demand!
