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 118 gallons of hot water in the test's first hour. Reheating lets it give 70 gallons beyond the 48 gallons in its tank. In the first hour, 43 of the 763 gas storage models give more hot water. The median gas storage model gives 78 gallons in the first hour of the test.

It was not listed as ENERGY STAR certified on Oct 26, 2026. In tests, 73% of the energy it uses ends up as hot water (UEF 0.73). The daily hot water use in the test, called its draw pattern, was high. Of 434 gas storage models with the same draw pattern, 54 have a higher UEF. For its type and draw pattern, the median UEF is 0.66. The water took in 82% of the energy used to reheat it (its recovery efficiency).

It is the basic model for PDVG62-50T62-NV 3** and PDVG62-50T62-PV 3*1. There are 5 more basic models with the same test figures. They are listed under 5 other brands, one each. For the full group, see the A. O. Smith GPDX-50L 3**.
