UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 119 gallons in the test, 1 gallon less than its 120-gallon sold size. Over one hour from a full tank, it gave 117 gallons in the test (its first-hour rating). Of 21 grid-enabled models, none gives more hot water in the first hour. The median grid-enabled model gives 85 gallons in the first hour of the test.
In tests, 90% of the energy it uses ends up as hot water (UEF 0.90). In the test, daily hot water use was set to high (its draw pattern). Its UEF is lower than that of 15 of the 21 grid-enabled models with its draw pattern. On its draw pattern, the median grid-enabled UEF is 0.92. 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 VAUGHN and VAUGHN THERMAL brands.
