UEF is the uniform energy factor. A dash means the model has no such figure.
It delivers 62 gallons of hot water in the test's first hour. Reheating lets it give 14 gallons beyond the 48 gallons in its tank. Of 477 electric storage models, 124 give more hot water in the first hour. Among electric storage models, the median first-hour rating is 55 gallons.
In tests, 93% of the energy went to hot water, so its UEF is 0.93. In the test, daily hot water use was set to medium (its draw pattern). Of 297 electric storage models with the same draw pattern, 20 have a higher UEF. For its type and draw pattern, the median UEF is 0.92. When it reheats water in the test, 98% of the energy it uses ends up in the water.
All of its test figures are shared by 2 other basic models. Of those, one or more are under the AMERICAN STANDARD WATER HEATERS and HTP brands. For the full group, see the AMERICAN STANDARD WATER HEATERS EVR052*2X*** page.
