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. Over one hour from a full tank, it gave 77 gallons in the test (its first-hour rating). Reheating lets it give 29 gallons beyond the 48 gallons in its tank. In the first hour, 418 of the 763 gas storage models give more hot water. The median gas storage model gives 78 gallons in its first hour.

As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 66% of the energy it uses ends up as hot water (UEF 0.66). The daily hot water use in the test, called its draw pattern, was high. Of 434 gas storage models with the same draw pattern, 213 have a higher UEF. Its UEF is the median for its type and draw pattern. Of the energy spent to reheat water, 79% goes into it (its recovery efficiency).

All 6 of its model numbers carry the same certified figures. There are 4 more basic models with the same test figures. Each of the 4 other brands lists one of them. For the full group, see the A. O. Smith GDV-50 3**.
