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 97 gallons of hot water in its first hour of use. Reheating lets it give 49 gallons beyond the 48 gallons in its tank. Among 763 gas storage models, 98 have a higher first-hour rating. Among gas storage models, the median first-hour rating is 78 gallons.

As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 72% of the energy went to hot water, so its UEF is 0.72. The daily hot water use in the test, called its draw pattern, was high. Of 434 gas storage models with the same draw pattern, 71 have a higher UEF. A UEF of 0.66 is the median for its type and draw pattern. Of the energy spent to reheat water, 81% goes into it (its recovery efficiency).

All 4 of its model numbers carry the same certified figures. There are 6 more basic models with the same test figures. Each of the 6 other brands lists one of them. For the full group, see the A. O. Smith GPVT-50 2** page.
