UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 107 gallons in the test, 13 gallons less than its 120-gallon sold size. Over one hour from a full tank, it gave 100 gallons in the test (its first-hour rating). Among 21 grid-enabled models, 4 have a higher first-hour rating. The median grid-enabled model gives 85 gallons in its first hour.
In tests, 91% of the energy it uses ends up as hot water (UEF 0.91). In the test, daily hot water use was set to high (its draw pattern). Of 21 grid-enabled models with the same draw pattern, 12 have a higher UEF and 6 a lower one. A UEF of 0.92 is the median for its type and draw pattern. Of the energy spent to reheat water, 98% goes into it (its recovery efficiency).
Its test figures match those of 2 other basic models. Those basic models are sold with VAUGHN and VAUGHN THERMAL as their brand names.
