Ruud PROPH80 T2 RH375-SO
4.07 UEF DOE CCD · 2026-09-19Grade B: 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).
The Ruud PROPH80 T2 RH375-SO uses 1,219 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 87 kWh below the class median of 1,306 kWh. The class is 194 electric tank models registered at the same draw pattern.
Energy use per year
1,219 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 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 14 of 194, lowest energy first.
Solid line: this model (1,219 kWh). Dashed line: the class median.

The annual figure for this model is 1,219 kWh of electricity. This site computed it, not the registry, so it is a modeled value and not a metered one. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, which is 4.07 for this unit. It also uses the DOE test's daily hot-water draw for the high draw pattern, and the source is DOE CCD, retrieved 2026-09-19. A household that draws more or less hot water than the test will see a different figure. The steps are set out in how the annual cost is calculated.
Within its class, this model has the 14th lowest energy use of 194. Its 1,219 kWh is 87 kWh below the class median of 1,306 kWh, placing it in the lowest quarter for energy use. The class holds only electric tank models registered at the high draw pattern, so the rank says nothing about other types. The high draw pattern describes a larger household, or one where showers and laundry overlap. This model lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 87 gallons. Its rated volume is 72 gallons; compare both figures with your own busiest hour.
The 1,219 kWh figure does not fit a smaller household with lighter use, which is tested at a different draw pattern. The 1,306 kWh class median is likewise specific to the high draw pattern. Running cost is not stated here because it depends on your own utility electricity rate. The cost calculator works it out from your ZIP. Installed price is shown in its own block with its source and date, as a modeled range and not a quote. To compare against other units in this class, find a same-class replacement by model number.
