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

Sold as 55 gallons, it holds 55 gallons in the test. Over one hour from a full tank, it gave 115 gallons in the test (its first-hour rating). Its tank holds 55 gallons, so reheating adds 60 gallons during the first hour.

In the test, 39% of its energy does not reach the hot water (UEF 0.61). When it reheats water in the test, 80% of the energy it uses ends up in the water.
