UEF is the uniform energy factor. A dash means the model has no such figure.

It holds 38 gallons in the test, 2 gallons less than its 40-gallon sold size. Over one hour from a full tank, it gave 64 gallons in the test (its first-hour rating). That is 26 gallons more than its tank holds, since it reheats during the hour. In the first hour, 629 of the 763 gas storage models give more hot water. The median gas storage model gives 78 gallons in its first hour.

It was not listed as ENERGY STAR certified on Oct 26, 2026. In tests, 61% of the energy went to hot water, so its UEF is 0.61. Its test ran at the medium level of daily hot water use. Among 288 gas storage models on its draw pattern, 72 have a higher UEF. For its type and draw pattern, the median UEF is 0.60. The water took in 74% of the energy used to reheat it (its recovery efficiency).

Its test figures match those of 3 other basic models. The A. O. Smith, American, and RELIANCE WATER HEATERS brands list one or more of them. You can find the whole group on the page for the A. O. Smith GDVNL-40L 1**.
