Rheem PROE38 S2 RH BCG
0.92 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 RH BCG, it uses 3,531 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That equals the median of the 426 electric tank models at this draw pattern, a difference of 0 kWh. It ranks 213th lowest in energy use.
Energy use per year
3,531 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 equal to the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 213 of 426, lowest energy first.
Solid line: this model (3,531 kWh). Dashed line: the class median.

This site calculates the 3,531 kWh figure; the registry does not publish it. The starting point is the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. That value is applied to the DOE test's daily hot-water draw for the medium draw pattern. The medium pattern represents a typical household with a busy morning of hot-water use. The figure holds only at that test draw. A home that draws more or less hot water will use a different amount of electricity. The source is the DOE CCD, retrieved 2026-09-19. The calculation steps are explained in how the annual cost is calculated. Its gap to the class median of 3,531 kWh is 0 kWh, so this model sits in the middle of its class, not at either end.
You can check the capacity figures on this listing against a household's busiest hour. The rated volume is 35 gallons. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 51 gallons. A household whose busiest hour stays within 51 gallons is within this unit's rated first-hour output. Some households need more than that in their busiest hour. They are outside what this rating covers, and the data does not show how the unit performs beyond that point. Those homes need a different size or draw pattern, which the water heater selector by fuel, space and size can filter for. For a like-for-like swap, the same-class replacement search by model number lists other electric tanks at the medium draw pattern.
This page does not state a running cost in the text. The cost of 3,531 kWh of electricity depends on your own utility tariff, and the registry data does not include that rate. The running-cost calculator for your ZIP applies your rate to this model's 3,531 kWh at the medium draw pattern. This model sits 0 kWh from the class median. At any one rate, its cost therefore equals that of a median-use model among the 426. The installed price range appears in its own block with its source and date. It is a modeled range, not a quote. This data does not show the running cost in a home that draws more or less hot water than the federal test.
