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. It delivers 84 gallons of hot water in the test's first hour. Its tank holds 48 gallons, so reheating adds 36 gallons during the first hour. Of 763 gas storage models, 209 give more hot water in the first hour. 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, 65% of the energy it uses ends up as hot water (UEF 0.65). Its test ran at the high level of daily hot water use. Of 434 gas storage models with the same draw pattern, 225 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).

Its test figures match those of 3 other basic models. Those basic models are sold with A. O. Smith, American, and RELIANCE WATER HEATERS as their brand names. You can find the whole group on the page for the A. O. Smith GDVNT-50L 1**.
