Rheem PROE40 M2 RH95
0.93 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 PROE40 M2 RH95, an electric tank water heater, it uses 3,493 kWh of electricity a year at the medium draw pattern. The draw pattern is the standard daily hot-water usage DOE tests against. That is 38 kWh below the class median of 3,531 kWh, ranking 153rd lowest of 426 models.
Energy use per year
3,493 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 153 of 426, lowest energy first.
Solid line: this model (3,493 kWh). Dashed line: the class median.

The 3,493 kWh figure does not appear in the registry itself. This site computes it from the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the medium pattern. For this model the UEF is 0.93, as listed in the DOE CCD, retrieved 2026-09-19. The result holds only at that test draw. A home that uses more or less hot water will use a different amount of electricity. The class here means the 426 models registered as an electric tank at the medium draw pattern. Ranked 153rd lowest, this model sits in the lower half of that class for energy use, but not at the low end. The full steps are set out in how the annual energy and cost figures are calculated.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 55 gallons for this unit. Its rated volume is 36 gallons. That matches the busy-morning demand that the medium draw pattern assumes. A household whose morning use stays within 55 gallons matches the conditions behind the 3,493 kWh estimate. A household that regularly draws more falls outside those conditions. The registry gives no energy figure for this model at a heavier load, so that figure is unknown. To compare units by other conditions, use the water heater selector by fuel, space and size. To check this model against others in its own class, use the same-class replacement search by model number.
This text does not state a running cost, because the cost depends on your own utility's electricity tariff. The running cost calculator for your ZIP computes it from 3,493 kWh and the rate for your ZIP. No fixed amount is given here. The same applies to the 38 kWh gap from the class median, whose yearly value depends on that rate. An installed price range appears in its own block on this page, with its source and date. It is a modeled installed-cost range, not a quote, and this text does not repeat its figures. For the Rheem PROE40 M2 RH95, energy use under conditions other than the medium test draw is not available.
