UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 39 gallons in the test, 1 gallon less than its 40-gallon sold size. It delivers 64 gallons of hot water in the test's first hour. Reheating lets it give 25 gallons beyond the 39 gallons in its tank. Of 763 gas storage models, 629 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, 60% of the energy it uses ends up as hot water (UEF 0.60). Its test ran at the medium level of daily hot water use. Among 288 gas storage models on its draw pattern, 88 have a higher UEF. Its UEF is the median for its type and draw pattern. The water took in 75% of the energy used to reheat it (its recovery efficiency).
It is sold under 5 model numbers in all. There are 4 more basic models with the same test figures. Each of them is listed under a different brand. You can find the whole group on the page for the A. O. Smith GDV-40 3**.
