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. Starting full, it gives 100 gallons of hot water in its first hour of use. In the first hour, 4 of the 21 grid-enabled models give more hot water. Among grid-enabled models, the median first-hour rating is 85 gallons.

In tests, 91% of the energy went to hot water, so its UEF is 0.91. Its test simulated a day of high hot water use (its draw pattern). Its UEF is lower than that of 12 of the 21 grid-enabled models with its draw pattern. A UEF of 0.92 is the median for its type and draw pattern. The water took in 98% of the energy used to reheat it (its recovery efficiency).

There are 2 more basic models with the same test figures. Of those, one or more are under the Hubbell and VAUGHN THERMAL brands. For the full group, see the Hubbell ME120 page.
