State ProLine XE 50-Gallon High-Efficiency Atmospheric Gas
State ProLine XE 50-Gallon High-Efficiency Atmospheric Gas Review
The State ProLine XE 50-Gallon High-Efficiency Atmospheric Gas is A.O. Smith's plumber-channel premium-tier atmospheric gas tank, sold under the State brand. The "XE" designation reflects the extended-warranty premium positioning.
Specs: 50 gallons stored, 40,000 BTU input, UEF 0.66 (atmospheric high-efficiency), 87-gallon FHR, 12-year tank and 12-year parts warranty. Atmospheric vent through B-vent. Self-cleaning dip tube, dual magnesium anode rods.
The XE positioning matches AO Smith Signature Premier at Lowe's — same 12-year warranty and ENERGY STAR certification through the plumber-channel State brand. Right answer for plumber-installed primary residences wanting longer warranty than standard ProLine tier.
About $799 plumber-channel pricing, $1,650 plumber-installed. For DIY purchases at Lowe's, AO Smith Signature Premier is the equivalent product.
