Rheem PROE50 T2 RH95

This site worked out the 3,493 kWh figure. The registry does not list it. The figure combines the model's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw that the DOE test sets for the medium pattern. The UEF of 0.93 comes from the DOE CCD, retrieved on 2026-09-19. The medium pattern stands for a typical household's daily use, as the DOE test defines it. Under that condition, this model ranks 153rd lowest for energy use among the 426 electric tank models registered at the medium pattern. You can see each step behind the figure in how the annual cost figures are calculated.

This model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 62 gallons. Its rated volume is 45 gallons. The 3,493 kWh figure only applies to a household whose daily use matches the medium draw pattern. A household that uses more hot water each day will use more electricity than that figure. A household that uses less will use less. This page has no figure for either case, so the size of the difference is unknown. If you need a replacement in the same class, the same-class replacement search by model number lists other electric tank models at the medium pattern. The water heater selector by fuel, space and size covers other fuels and sizes.

This text does not state a running cost. What 3,493 kWh of electricity a year costs depends on your own utility tariff. The cost calculator for your own ZIP applies your local electricity rate to this model's figure. The installed price range is shown in its own block on this page, with its source and date. That range is modeled and is not a quote from an installer. Plumbers and sellers checking a claim should note that this page does not have the reader's tariff. Any running-cost figure depends on that tariff, so this text cannot give one.
