Richmond PROPH50 T2 RH375-SO
3.88 UEF DOE CCD · 2026-09-19Grade A: 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 T2 RH375-SO, it uses 837 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,694 kWh below the 3,531 kWh median of the 426 electric tank models at the same draw pattern. It ranks 5th lowest in energy use.
Energy use per year
837 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 5 of 426, lowest energy first.
Solid line: this model (837 kWh). Dashed line: the class median.

UEF 3.88 · Grade A Price it on your ZIP
The 837 kWh figure does not appear in the registry itself. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, and the daily hot-water draw that the DOE test sets for the medium draw pattern. For the PROPH50 T2 RH375-SO, the registry lists a UEF of 3.88. DOE uses the medium pattern to represent a typical household's use, including a busy morning. The UEF and the class data come from the DOE CCD, retrieved 2026-09-19. Every model in the class is tested against the same fixed draw, so the figure compares units under equal conditions. It is not a meter reading from any real home. The steps behind the calculation are set out in how this site calculates annual energy and cost.
The registry gives this electric tank a rated volume of 45 gallons. It also gives a first hour rating, the gallons of hot water available in the first hour from a full tank, of 67 gallons. Together with the medium draw pattern, these figures describe the household the test assumes. For a home whose daily use sits near that pattern, the 837 kWh estimate is the relevant point of comparison. The class position given above holds only among the 426 electric tank models at medium draw. It says nothing about gas units or other heater types. To compare this model with other fuels or tank sizes, use the water heater selector by fuel, space and size.
The 837 kWh figure does not describe homes whose hot-water use differs from the medium draw pattern. A household that draws much more or much less each day would use a different amount of energy. That amount is not available in the registry data. The same limit applies if peak demand often exceeds the 67-gallon first hour rating. The running cost is not stated here because it depends on your own utility's electricity tariff. You can work it out from your ZIP with the running-cost calculator for your own ZIP. The installed price range has its own block on this page. It is a modeled range, not a quote.
