UEF is the uniform energy factor. A dash means the model has no such figure.
It delivers 52 gallons of hot water in the test's first hour. Its tank holds 42 gallons, so reheating adds 10 gallons during the first hour. Of 477 electric storage models, 279 give more hot water in the first hour. The median electric storage model gives 55 gallons in its first hour.
In the test, 8% of its energy does not reach the hot water (UEF 0.92). Its test simulated a day of medium hot water use (its draw pattern). Among 297 electric storage models on its draw pattern, 81 have a higher UEF. Its UEF is the median for its type and draw pattern. The water took in 98% of the energy used to reheat it (its recovery efficiency).
All of its test figures are shared by 2 other basic models. Of those, one or more are under the Ariston and Lennox brands.
