UEF is the uniform energy factor. A dash means the model has no such figure.

Sold as 80 gallons, it holds 80 gallons in the test. Starting full, it gives 83 gallons of hot water in its first hour of use. Its tank holds 80 gallons, so reheating adds 3 gallons during the first hour. Of 21 grid-enabled models, 12 give more hot water in the first hour. The median grid-enabled model gives 85 gallons in its first hour.

In tests, 92% of the energy it uses ends up as hot water (UEF 0.92). In the test, daily hot water use was set to high (its draw pattern). Of 21 grid-enabled models with the same draw pattern, 2 have a higher UEF. For its type and draw pattern, its UEF sits at the median. 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.
