Whirlpool 75-Gallon Natural Gas Water Heater
Whirlpool 75-Gallon Natural Gas Water Heater Review
The Whirlpool 75-Gallon Natural Gas Water Heater is Whirlpool's large-capacity gas tank, built by A.O. Smith with Whirlpool branding for the Lowe's channel. Sized for 5+ person households with overlapping demand.
Specs: 75 gallons stored, 76,000 BTU input, UEF 0.60, 110-gallon FHR, 6-year tank and parts warranty. Atmospheric vent through B-vent.
The combination of 75-gallon reservoir + 76K BTU burner serves 5+ person households comfortably. About $1,000 at Lowe's, $2,300 installed.
For households considering very-large-capacity solutions, the Whirlpool 75-gal sits between standard 50-gallon (insufficient) and tankless conversion ($4,000+, endless hot water). For households with basement install supporting heat-pump, AO Smith Voltex Premium HPTU-66 or HPTU-80 heat-pump alternatives offer dramatically lower operating cost.
