Richmond PROE36 S2 RH CG
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).
For anyone verifying the Richmond PROE36 S2 RH CG: it uses 3,531 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 0 kWh from the median of 3,531 kWh across the 426 electric tank models registered at the same draw pattern.
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.

The 3,531 kWh figure is calculated by this site. The registry does not publish it. The calculation uses 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 draw pattern. For this model the UEF is 0.92, taken from the DOE CCD as retrieved on 2026-09-19. The result applies only at that federal test draw. A home whose daily hot-water use differs from the test draw will use a different amount of electricity than 3,531 kWh. The registry data does not show how large that difference would be for any one home. When you check a listing, compare figures that share the same conditions: the medium draw pattern, electricity as the fuel and the federal test. The steps are set out in how the annual cost is calculated.
This unit ranks 213th lowest in energy use among the 426 electric tank models at the medium draw pattern. It sits at the class median given above. The medium pattern represents a typical household's hot-water use on a busy morning. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 51 gallons. Its rated volume is 33 gallons. A household that uses no more than 51 gallons in its busiest hour matches the conditions behind the energy figure. A household that regularly needs more than 51 gallons in that hour falls outside those conditions. Registry figures for this model at other draw patterns are not available here. To compare other units, use the selector by fuel, space and size or 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 page calculates it from your ZIP by applying that tariff to 3,531 kWh a year at the medium draw pattern. Two households with this model and the same hot-water use will pay different amounts if their tariffs differ. This model's energy use equals the class median. On any single rate, its calculated running cost therefore matches that of a model at the class median. To see the figure on your rate, use the cost calculator on your own ZIP. The installed price appears in a separate block on this page with its own source and date. It is a modeled range, not a quote.
