Rheem PROPH65 T0 RH120-M
3.12 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 Rheem PROPH65 T0 RH120-M, this electric tank uses 1,041 kWh of electricity a year. That figure applies at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,490 kWh below the class median of 3,531 kWh, ranking 112th lowest in energy use of 426 comparable models.
Energy use per year
1,041 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 112 of 426, lowest energy first.
Solid line: this model (1,041 kWh). Dashed line: the class median.

UEF 3.12 · Grade C Price it on your ZIP
This site calculated the 1,041 kWh figure; the registry does not publish it. It combines the model's registered UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium pattern. For the Rheem PROPH65 T0 RH120-M, the UEF is 3.12. The medium pattern represents a typical household's hot-water use, including a busy morning. The figure therefore holds only at that federal test draw. A home that draws more or less hot water each day will not use exactly 1,041 kWh. The registry gives no figure for other usage levels, so none is shown here. The same energy figure feeds the running cost, as set out in how the annual cost is calculated.
The class is the 426 models registered as an electric tank at the medium draw pattern. A rank of 112th places this model below the class median, but not at the lowest position. Fit depends on demand as well as energy. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 63 gallons. The rated volume is 59 gallons. A household whose busiest hour stays within 63 gallons is inside what the test measured. A household that routinely draws more in one hour is outside that rating. This page has no data on how the unit performs there. To compare other tanks, use the water heater selector by fuel, space and size.
The text does not state a running cost. The cost of 1,041 kWh a year depends on your own utility's electricity tariff, which this page does not know in advance. The page computes it from your ZIP rather than estimating it here. The cost calculator on your own ZIP applies your rate to this model's energy figure at the medium draw pattern. The installed price range appears in its own block with its source and date. That block is a modeled range, not a quote. If you are matching a unit, you can find a same-class replacement by model number using PROPH65 T0 RH120-M. The energy data comes from the DOE CCD, retrieved 2026-09-19.
