ENERGY STAR certified models

State HPTA-50 2**: ENERGY STAR certified models
Model number	Storage volume (gal)	UEF	First-hour rating (gal)	Recovery efficiency

It holds 46 gallons in the test, 4 gallons less than its 50-gallon sold size. Over one hour from a full tank, it gave 65 gallons in the test (its first-hour rating). That is 19 gallons more than its tank holds, since it reheats during the hour. Of 481 heat pump models, 346 give more hot water in the first hour. The median heat pump model gives 72 gallons in its first hour.

It has 2 model numbers that are ENERGY STAR certified. For each unit of energy it uses, 3.68 units end up in the hot water (its UEF). A UEF above 1 is possible because it moves heat from the air into the water. Its test ran at the medium level of daily hot water use. Among 226 heat pump models on its draw pattern, 110 have a higher UEF. For its type and draw pattern, its UEF sits at the median. While it reheats, the water gains 416% of the energy it uses (its recovery efficiency).

It is the basic model for CSHP-50 2** and HPAX-50-DHPT 2**. There are 4 more basic models with the same test figures. Each of them is listed under a different brand. For the full group, see the A. O. Smith HPTA-50 2** page.
