It holds 49 gallons in the test, 1 gallon less than its 50-gallon sold size. It delivers 79 gallons of hot water in the test's first hour. Its tank holds 49 gallons, so reheating adds 30 gallons during the first hour. Of 763 gas storage models, 344 give more hot water in the first hour. The median gas storage model gives 78 gallons in its first hour.

On Oct 26, 2026, this heater was not listed as ENERGY STAR certified. In tests, 72% of the energy went to hot water, so its UEF is 0.72.
