Specs: 66 gallons stored, two 4500W heating elements (240V), UEF 0.93, 80-gallon FHR, 6-year tank and parts warranty. Glass-lined steel tank, magnesium anode rod.
The 66-gallon Whirlpool serves 4-5 person households. Same A.O. Smith engineering as AO Smith Voltex 66-gallon Electric with Whirlpool branding.
