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

It holds 49 gallons in the test, 1 gallon less than its 50-gallon sold size. Over one hour from a full tank, it gave 79 gallons in the test (its first-hour rating). Its tank holds 49 gallons, so reheating adds 30 gallons during the first hour. Among 763 gas storage models, 344 have a higher first-hour rating. Among gas storage models, the median first-hour rating is 78 gallons.
