UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 39 gallons in the test, 1 gallon less than its 40-gallon sold size. It delivers 65 gallons of hot water in the test's first hour. Reheating lets it give 26 gallons beyond the 39 gallons in its tank. In the first hour, 600 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.
As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 58% of the energy went to hot water, so its UEF is 0.58. In the test, daily hot water use was set to medium (its draw pattern). Of 288 gas storage models with the same draw pattern, 230 have a higher UEF and 11 a lower one. A UEF of 0.60 is the median for its type and draw pattern. The water took in 77% of the energy used to reheat it (its recovery efficiency).
Its 3 model numbers are 42X40SF3, PROG40S-35P RH62, and PROG40S-38N RH62. 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.
