It holds 47 gallons in the test, 3 gallons less than its 50-gallon sold size. Starting full, it gives 58 gallons of hot water in its first hour of use. Its tank holds 47 gallons, so reheating adds 11 gallons during the first hour. Among 481 heat pump models, 414 have a higher first-hour rating. The median heat pump model gives 72 gallons in its first hour.

Under this basic model, 2 model numbers are ENERGY STAR certified. For each unit of energy it uses, 3.46 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. In the test, daily hot water use was set to medium (its draw pattern). Its UEF is lower than that of 182 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 373%, because it takes heat from the air as it reheats water.

There are 2 more basic models with the same test figures. The Hubbell and VAUGHN THERMAL brands list one or more of them. For the full group, see the Hubbell ME50HPT page.
