It holds 36 gallons in the test, 4 gallons less than its 40-gallon sold size. Over one hour from a full tank, it gave 60 gallons in the test (its first-hour rating). Reheating lets it give 24 gallons beyond the 36 gallons in its tank. Of 481 heat pump models, 371 give more hot water in the first hour. The median heat pump model gives 72 gallons in the first hour of the test.

It is ENERGY STAR certified under its single model number. In the test, it gives 3.50 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 ran at the medium level of daily hot water use. Its UEF is lower than that of 158 of the 226 heat pump models with its draw pattern. A UEF of 3.68 is the median for its type and draw pattern. Its recovery efficiency is 430%, because it takes heat from the air as it reheats water.

Its test figures match those of 4 other basic models. Of those, one or more are under the Friedrich and Rheem brands. You can find the whole group on the page for the Rheem PRO H40 T2 RH310BM.

It may qualify for 21 rebate programs. Another 7 programs may accept it if it meets their other terms.
