It holds 81 gallons in the test, 1 gallon more than its 80-gallon sold size. Starting full, it gives 95 gallons of hot water in its first hour of use. Reheating lets it give 14 gallons beyond the 81 gallons in its tank. Of 481 heat pump models, 17 give more hot water in the first hour. The median heat pump model gives 72 gallons in its first hour.

All 2 of its model numbers are 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. The daily hot water use in the test, called its draw pattern, was high. Its UEF is lower than that of 112 of the 237 heat pump models with its draw pattern. Its UEF is the median for its type and draw pattern. Its recovery efficiency is 428%, because it takes heat from the air as it reheats water.

It is sold as CHPA-80 2** and HPPA080KD 2**. There are 4 more basic models with the same test figures. Each of them is listed under a different brand. You can find the whole group on the page for the A. O. Smith HPTA-80 2**.
