American Standard 50-Gallon Natural Gas Water Heater
American Standard 50-Gallon Natural Gas Water Heater Review
The American Standard 50-Gallon Natural Gas is the American Standard-branded variant of an AO Smith-built 50-gallon gas tank. American Standard is one of AO Smith's distribution brands, primarily sold through hardware stores and plumbing supply houses rather than the big-box channels.
Specs: 40,000 BTU input, UEF 0.58, 81-gallon first-hour rating, 6-year tank and 6-year parts warranty. Atmospheric vent. Standard residential gas control with electronic ignition. Magnesium anode rod, polyurethane foam insulation.
The American Standard line sits between AO Smith's budget Reliance brand and the mainstream ProMax/Conservationist lines. The hardware is functionally equivalent to AO Smith ProMax with American Standard branding for hardware store and supply house channels.
Right buyer: hardware store / supply house shopper who has brand recognition with American Standard from their plumbing fixtures line. About $549 unit, $1,250 installed. The 6-year warranty matches typical landlord replacement cycles or shorter ownership horizons. For longer-term primary residences, AO Smith Signature Premier (12-year warranty) is usually the better economic choice.
