UEF is the uniform energy factor. A dash means the model has no such figure.
It holds 30 gallons in the test, 2 gallons less than its 32-gallon sold size. It delivers 125 gallons of hot water in the test's first hour. Its tank holds 30 gallons, so reheating adds 95 gallons during the first hour. Of 3 oil storage models, 2 give more hot water in the first hour. Among oil storage models, the median first-hour rating is 140 gallons.
In the test, 36% of its energy does not reach the hot water (UEF 0.64). In the test, daily hot water use was set to high (its draw pattern). Its UEF is lower than that of 2 of the 3 oil storage models with its draw pattern. A UEF of 0.67 is the median for its type and draw pattern. When it reheats water in the test, 78% of the energy it uses ends up in the water.
