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

It holds 48 gallons in the test, 2 gallons less than its 50-gallon sold size. Over one hour from a full tank, it gave 97 gallons in the test (its first-hour rating). Its tank holds 48 gallons, so reheating adds 49 gallons during the first hour. In the first hour, 98 of the 763 gas storage models give more hot water. The median gas storage model gives 78 gallons in its first hour.
