Ruud PROPH80 T0 RH120-M
3.46 UEF DOE CCD · 2026-09-19Grade C: where this UEF sits among the 194 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are checking the Ruud PROPH80 T0 RH120-M, this electric tank uses 1,434 kWh of electricity a year. That figure applies at the high draw pattern, the standard daily hot-water usage DOE tests against. It is 128 kWh above the 1,306 kWh median of its class. It ranks 131st lowest in energy use of 194 models.
Energy use per year
1,434 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 above the median of 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 131 of 194, lowest energy first.
Solid line: this model (1,434 kWh). Dashed line: the class median.

UEF 3.46 · Grade C Price it on your ZIP
This site computed the 1,434 kWh figure; the registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. This model's UEF is 3.46, from DOE CCD data retrieved 2026-09-19. The figure holds only at that test draw. A household that uses more or less hot water each day will use a different amount of electricity. The comparison group is the 194 models registered as an electric tank at the high draw pattern. Within that group, this unit sits in the second-highest quarter for energy use. For how the page turns this energy figure into a yearly cost, see how the annual cost is calculated.
The high draw pattern represents a larger household, or one where showers and laundry overlap. For that kind of use, the registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 84 gallons. The rated volume is 72 gallons. A plumber or seller checking a sizing claim can compare these two values with the model label. Whether that output covers a specific home depends on the home's peak demand, and this page does not know that demand. This data does not include the model's energy use at a lower draw pattern. To compare other units by fuel, space and size, use the water heater selector.
This text does not state the running cost. It depends on your own utility's electricity tariff, so the page calculates it from your ZIP. Enter your ZIP in the cost calculator for your ZIP to price the 1,434 kWh yearly figure at your rate. The gap above the class median, noted above, is priced at that same rate. If you want a unit below the 1,306 kWh median, you will need a different model. The page to find a same-class replacement by model number lists other models in this class. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote.
