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. Starting full, it gives 76 gallons of hot water in its first hour of use. Its tank holds 48 gallons, so reheating adds 28 gallons during the first hour. In the first hour, 429 of the 763 gas storage models give more hot water. Among gas storage models, the median first-hour rating is 78 gallons.

It was not listed as ENERGY STAR certified on Oct 26, 2026. In tests, 65% of the energy went to hot water, so its UEF is 0.65. Its test simulated a day of high hot water use (its draw pattern). Among 434 gas storage models on its draw pattern, 225 have a higher UEF. For its type and draw pattern, the UEF runs from 0.61 to 0.90. The water took in 81% of the energy used to reheat it (its recovery efficiency).

It is sold under 8 model numbers in all. All of its test figures are shared by 3 other basic models. Of those, one or more are under the Friedrich, Richmond, and Ruud brands.
