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

Over one hour from a full tank, it gave 78 gallons in the test (its first-hour rating). That is 30 gallons more than its tank holds, since it reheats during the hour. Of 763 gas storage models, 366 give more hot water in the first hour. Its first-hour rating matches the median for gas storage models.

On Oct 26, 2026, this heater was not listed as ENERGY STAR certified. In tests, 64% of the energy it uses ends up as hot water (UEF 0.64). Its test simulated a day of high hot water use (its draw pattern). Among 434 gas storage models on its draw pattern, 255 have a higher UEF. A UEF of 0.66 is the median for its type and draw pattern. When it reheats water in the test, 77% of the energy it uses ends up in the water.

It is sold as GS6-50-BCUT 5** and GSX-50-BCUT 5**. Its test figures match those of 4 other basic models. They are listed under 4 other brands, one each. For the full group, see the A. O. Smith G9-UT5040NVR 5**.
