Richmond PROPH50 T0 RH120-M
3 UEF DOE CCD · 2026-09-19Grade C: 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 Richmond PROPH50 T0 RH120-M, this site computes 1,083 kWh of electricity a year for it. That figure applies at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,448 kWh below the 3,531 kWh median of the 426 electric tank models registered at that draw pattern.
Energy use per year
1,083 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 116 of 426, lowest energy first.
Solid line: this model (1,083 kWh). Dashed line: the class median.

UEF 3 · Grade C Price it on your ZIP
The registry does not print the 1,083 kWh figure. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, and from the DOE test's daily hot-water draw for the medium pattern. This model's UEF is 3. The medium pattern stands for a typical medium-sized household on the federal test schedule. The inputs come from the DOE Compliance Certification Database, retrieved 2026-09-19. A household that draws more hot water than the test day will use more than 1,083 kWh, and one that draws less will use less. The size of that difference for any one home is not available, because the registry gives only the test-day figure. The steps are set out in how this site calculates annual energy and running cost.
Among the 426 electric tank models registered at the medium draw pattern, this one ranks 116th lowest in energy use. That places it in the second-lowest quarter of its class, 2,448 kWh below the class median of 3,531 kWh. Some models in the same class use less energy on the same test. The ranking compares test-day energy only; the registry does not record noise or footprint. The figure fits a household whose use resembles the medium pattern. This model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 55 gallons. Its rated volume is 46 gallons. A home with heavier morning demand than 55 gallons may not match the medium-pattern figure. To compare other units in this class, use the same-class replacement search by model number.
Running cost is not stated in this text. It depends on your own utility's electricity tariff, which this page does not know until you enter a ZIP. The running-cost calculator for your own ZIP applies your local electricity rate to the 1,083 kWh test-day figure. At any single rate, the cost gap to a median model in the class follows the 2,448 kWh energy gap. Your actual bill is not available here, because it also depends on your household's real hot-water use. The installed-price range appears in its own block on this page, with its source and date. It is a modeled range for installed cost, not a quote, and this text does not restate its figures.
