UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 47 gallons in the test, 3 gallons less than its 50-gallon sold size. Over one hour from a full tank, it gave 56 gallons in the test (its first-hour rating). Its tank holds 47 gallons, so reheating adds 9 gallons during the first hour. Of 477 electric storage models, 197 give more hot water in the first hour. Among electric storage models, the median first-hour rating is 55 gallons.
In the test, 8% of its energy does not reach the hot water (UEF 0.92). In the test, daily hot water use was set to medium (its draw pattern). Among 297 electric storage models on its draw pattern, 81 have a higher UEF. Its UEF is the median for its type and draw pattern. When it reheats water in the test, 98% of the energy it uses ends up in the water.
