Ruud PROE50 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 Ruud PROE50 M2 RH95, this electric tank uses 3,493 kWh of electricity a year. That figure is for the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 38 kWh below the class median of 3,531 kWh, ranking 153rd lowest in energy use of 426 comparable 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.

UEF 0.93 · Grade G Price it on your ZIP
The 3,493 kWh figure is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw the DOE test sets for the medium draw pattern. This model's UEF is 0.93, taken from the DOE CCD, retrieved 2026-09-19. The class is the 426 models registered as an electric tank at the medium draw pattern. Their median is 3,531 kWh a year, and this model sits 38 kWh below it. The figure holds only at the test's daily draw. A household that uses more or less hot water than that will see a different total. The steps are set out in how the annual energy and cost are calculated.
The medium draw pattern stands for a typical household's daily hot-water use as DOE defines it. This model has a rated volume of 45 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons. A home whose busiest hour stays within 62 gallons fits the condition the energy figure was tested under. A home whose peak demand runs above that falls outside it, and the 3,493 kWh figure would not describe its use. The figure also covers electricity only; it does not compare this unit with gas or heat pump models. To look across fuels and sizes, use the water heater selector by fuel, space and size. To match this class, try finding a same-class replacement by model number.
Running cost is not stated in this text because it depends on your own utility's electricity tariff. The page computes it from your ZIP by applying your local rate to the 3,493 kWh yearly figure at the medium draw pattern. Any cost you see therefore carries the same condition as the energy figure: the federal test's daily draw. If your electricity rate is not known for your ZIP, that cost is not available here. You can enter a ZIP in the running cost calculator for your own ZIP. The installed price range appears in its own block with its source and date. That range is modeled, not a quote, and this text does not restate it.
