UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 48 gallons in the test, 2 gallons less than its 50-gallon sold size. It delivers 85 gallons of hot water in the test's first hour. Its tank holds 48 gallons, so reheating adds 37 gallons during the first hour. Of 763 gas storage models, 192 give more hot water in the first hour. The median gas storage model gives 78 gallons in the first hour of the test.
On Oct 26, 2026, this heater was not listed as ENERGY STAR certified. In tests, 64% of the energy it uses ends up as hot water (UEF 0.64).
