Friedrich PROH50 T2 FD350BM

It holds 45 gallons in the test, 5 gallons less than its 50-gallon sold size. Starting full, it gives 67 gallons of hot water in its first hour of use. Its tank holds 45 gallons, so reheating adds 22 gallons during the first hour. Among 481 heat pump models, 287 have a higher first-hour rating. The median heat pump model gives 72 gallons in the first hour of the test.

The single model number sold under it is ENERGY STAR certified. For each unit of energy it uses, 3.50 units end up in the hot water (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 medium. Of 226 heat pump models with the same draw pattern, 158 have a higher UEF. On its draw pattern, the median heat pump UEF is 3.68. Its recovery efficiency is 400%, because it takes heat from the air as it reheats water.

All of its test figures are shared by 11 other basic models. Of those, one or more are under the Rheem and Ruud brands. You can find the whole group on the page for the Rheem PRO H50 T2 RH310BM.

In 18 states, 18 rebate programs may accept it. It may qualify for 6 more if it meets terms its figures do not show.
