It holds 45 gallons in the test, 5 gallons less than its 50-gallon sold size. It delivers 67 gallons of hot water in the test's first hour. That is 22 gallons more than its tank holds, since it reheats during the hour.

It has 4 model numbers that are ENERGY STAR certified. In the test, it gives 3.50 units of hot water energy per unit it uses (its UEF). Pulling heat from the air lets its UEF pass 1. Its test simulated a day of medium hot water use (its draw pattern). While it reheats, the water gains 400% of the energy it uses (its recovery efficiency).

All 4 of its model numbers carry the same certified figures. Its test figures match those of 12 other basic models. Of those, one or more are under the Rheem and Ruud brands.

In 18 states, 18 rebate programs may accept it. Another 6 rebate programs may accept it if it meets their other terms.
