Rheem PROPH50 T2 RH400-30
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 Rheem PROPH50 T2 RH400-30, this electric tank uses 837 kWh of electricity a year. That figure applies at the medium draw pattern, the standard daily hot-water usage DOE tests against. It is 2,694 kWh below the 3,531 kWh median of the 426 electric tanks registered at the same draw pattern, and it ranks 5th lowest.
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 is calculated by this site. The registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw that the DOE test sets for the medium draw pattern. For the PROPH50 T2 RH400-30, the UEF is 3.88, taken from the DOE CCD as retrieved on 2026-09-19. The annual figure therefore applies at the federal test's draw, not at any particular home's use. A household that draws more hot water each day than the test assumes would use more electricity than 837 kWh. A household that draws less would use less. Each input and step is set out in how this site calculates annual energy and running cost.
The medium draw pattern stands for a typical household of moderate size on a busy morning. This tank 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 67 gallons. Whether that is enough for a given home depends on the home's peak use, and this page does not have that information. The 5th ranking out of 426 applies only among electric tanks at the medium draw pattern. This page has no energy figure for this model at a higher or lower draw pattern, so the ranking says nothing about a household with heavier daily use. To compare heaters by fuel, space and size, use the water heater selector.
The running cost is not given here because it depends on your own utility's electricity tariff. The page calculates it from your ZIP code instead. What the data does show is the energy gap: 2,694 kWh a year below the class median of 3,531 kWh, at the medium draw pattern. What that gap is worth depends on your rate per kWh, so the same model costs different amounts to run in different service areas. To see the figure for your rate, use the running cost calculator for your own ZIP. The installed price range appears in its own block, with its source and date. It is a modeled range, not a quote. To check another model in the same class, use find a same-class replacement by model number.
