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. It delivers 73 gallons of hot water in the test's first hour. That is 35 gallons more than its tank holds, since it reheats during the hour. In the first hour, 477 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.

As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In the test, 33% of its energy does not reach the hot water (UEF 0.67). Its test simulated a day of medium hot water use (its draw pattern). Of 288 gas storage models with the same draw pattern, 19 have a higher UEF and 262 a lower one. On its draw pattern, the median gas storage UEF is 0.60. When it reheats water in the test, 79% of the energy it uses ends up in the water.

It is the basic model for PV40N 2** and PV40P 2*1. Its test figures match those of 6 other basic models. They are listed under 6 other brands, one each. For the full group, see the A. O. Smith GPVL-40 2** page.
