UEF is the uniform energy factor. A dash means the model has no such figure.

It holds 29 gallons in the test, 1 gallon less than its 30-gallon sold size. Starting full, it gives 62 gallons of hot water in its first hour of use. Reheating lets it give 33 gallons beyond the 29 gallons in its tank. In the first hour, 671 of the 763 gas storage models give more hot water. 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 the test, 40% of its energy does not reach the hot water (UEF 0.60). Its test ran at the medium level of daily hot water use. Of 288 gas storage models with the same draw pattern, 88 have a higher UEF. On its draw pattern, its UEF is also the median gas storage UEF. The water took in 73% of the energy used to reheat it (its recovery efficiency).
