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 66 gallons of hot water in the test's first hour. Its tank holds 39 gallons, so reheating adds 27 gallons during the first hour. Among 763 gas storage models, 585 have a higher first-hour rating. 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, 58% of the energy went to hot water, so its UEF is 0.58. Its test ran at the medium level of daily hot water use. Its UEF is lower than that of 230 of the 288 gas storage models with its draw pattern. On its draw pattern, the median gas storage UEF is 0.60. Of the energy spent to reheat water, 75% goes into it (its recovery efficiency).

It is sold as 12GR40S-36PF and 12GR40S-40F. There are 3 more basic models with the same test figures. Of those, one or more are under the Friedrich, Rheem, and Ruud brands. For the full group, see the Rheem PROG40S-40N RH62 page.
