Sold as 50 gallons, it holds 45 gallons in the test. It delivers 65 gallons of hot water in the test's first hour. Among 481 heat pump models, 346 have a higher first-hour rating. Among heat pump models, the median first-hour rating is 72 gallons.

The single model number sold under it is ENERGY STAR certified. In the test, it gives 3.88 units of hot water energy per unit it uses (its UEF). It moves heat from the air rather than making it, so its UEF passes 1. Its test simulated a day of medium hot water use (its draw pattern). Of 226 heat pump models with the same draw pattern, 6 have a higher UEF and 204 a lower one. A UEF of 3.68 is the median for its type and draw pattern. Its recovery efficiency is 412%, because it takes heat from the air as it reheats water.

Its test figures match those of one other basic model. The brand name on that one is PHNIX.

In 17 states, 17 rebate programs may accept it. It may qualify for 5 more if it meets terms its figures do not show.
