Rheem PROE38 S2 RH93 SB
0.94 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 426 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are checking the Rheem PROE38 S2 RH93 SB against the registry, it uses 3,456 kWh of electricity a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 75 kWh below the 3,531 kWh median of the 426 electric tank models registered at that pattern.
Energy use per year
3,456 kWh a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.
That is below the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 137 of 426, lowest energy first.
Solid line: this model (3,456 kWh). Dashed line: the class median.

The registry does not list the 3,456 kWh figure. This site calculated it from the model's UEF, the ratio of hot water delivered to energy used, which the registry lists as 0.94. That ratio was combined with the DOE test's daily hot-water draw for the medium draw pattern. The medium pattern stands for a typical household's use on a busy morning. The UEF comes from the DOE CCD, retrieved 2026-09-19. The 3,456 kWh figure therefore applies at the federal test's draw, not at your own household's measured use. The page on how the annual cost is calculated sets out each step.
The class comparison counts only the 426 models registered as an electric tank at the medium draw pattern. Within that group, this unit ranks 137th lowest for energy use. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 59 gallons. Its rated volume is 35 gallons. These figures describe a household whose daily use matches the medium draw pattern. For a household that draws more hot water than that pattern, the 3,456 kWh figure does not apply. How far its use would differ is not available here. To check other units in the same class, you can find a same-class replacement by model number.
No running cost is given in this text, because it depends on your own utility electricity tariff. The 75 kWh gap below the 3,531 kWh median is a difference in energy. What that gap is worth in money changes with your tariff, so it is not stated here. The cost block on this page works out the running cost from your ZIP. For other models, the cost calculator on your own ZIP uses the same method. The installed-cost range appears in its own block, with its source and date. It is a modeled range, not a quote.
