Whirlpool Energy Smart 40-Gallon Electric Water Heater
Whirlpool Energy Smart 40-Gallon Electric Water Heater Review
The Whirlpool Energy Smart 40-Gallon Electric is the smaller-capacity sibling of the Whirlpool Energy Smart 50-Gallon Electric. Built by A.O. Smith with Whirlpool branding for Lowe's channel. The Energy Smart positioning adds a "smart" control module versus standard Whirlpool electric.
Specs: 40 gallons stored, two 4500W heating elements (240V), UEF 0.95, 52-gallon FHR, 9-year tank warranty (versus 6-year for standard Whirlpool 40-gal Electric). ENERGY STAR Most Efficient certified. The Energy Smart control system monitors usage patterns and adjusts heating schedules.
About $649 at Lowe's, $1,200 installed. For most longer-term primary residence buyers, either A.O. Smith Voltex Hybrid 40-gallon (heat-pump option with much lower operating cost) or Rheem Marathon 40-gallon (lifetime warranty) is a better economic choice.
The Energy Smart line sits in an awkward middle ground — better than budget but not as compelling as truly differentiated alternatives.
