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. It delivers 100 gallons of hot water in the test's first hour. Of 21 grid-enabled models, 4 give more hot water in the first hour. The median grid-enabled model gives 85 gallons in the first hour of the test.
In the test, 9% of its energy does not reach the hot water (UEF 0.91). The daily hot water use in the test, called its draw pattern, was high. Among 21 grid-enabled models on its draw pattern, 12 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. The Hubbell and VAUGHN brands list one or more of them. For the full group, see the Hubbell ME120.
