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 78 gallons of hot water in its first hour of use. That is 30 gallons more than its tank holds, since it reheats during the hour. In the first hour, 366 of the 763 gas storage models give more hot water. Its first-hour rating matches the median for gas storage models.

It was not listed as ENERGY STAR certified on Oct 26, 2026. In the test, 30% of its energy does not reach the hot water (UEF 0.70). Its test ran at the high level of daily hot water use. Of 434 gas storage models with the same draw pattern, 111 have a higher UEF. For its type and draw pattern, the median UEF is 0.66. When it reheats water in the test, 79% of the energy it uses ends up in the water.

It is sold as PROG50S-32P RU67 PV and PROG50S-36N RU67 PV. There are 3 more basic models with the same test figures. Those basic models are sold with Friedrich, Rheem, and Richmond as their brand names. For the full group, see the Rheem PROG50S-36N RH67 PV page.
