Whirlpool 65-Gallon Natural Gas Water Heater Review
The Whirlpool 65-Gallon Natural Gas Water Heater is Whirlpool's mid-large capacity gas tank, built by A.O. Smith with Whirlpool branding for Lowe's channel. 65-gallon covers 4-5 person households.
Specs: 65 gallons stored, 50,000 BTU input, UEF 0.62, 95-gallon FHR, 6-year tank and parts warranty. Atmospheric vent through B-vent.
The 65-gallon capacity bridges the gap between standard 50-gallon and 75-gallon gas tanks. Right answer for 4-5 person households where 50-gallon would be tight but 75-gallon is unnecessary.
About $899 at Lowe's, $1,800 installed.
Pros
- Natural gas combustion — faster recovery than electric resistance at comparable tank size
- 65-gallon capacity — right-sized for 3–4 person households with standard usage patterns
- 108-gallon first-hour rating — handles morning-rush simultaneous demand without shortfall
Cons
- Below-average UEF 0.62 — modern standard models reach 0.65+, condensing 0.95+
- 6-year warranty — below the 8–12 year average for premium models in this class
- Atmospheric venting requires vertical B-vent — less routing flexibility than power-vent or condensing alternatives
