Rheem PROPH80 T2 RH400-30

4.07 UEF DOE CCD · 2026-09-19
B

Grade 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).

Checking the Rheem PROPH80 T2 RH400-30 against its registry entry? At the high draw pattern, the standard daily hot-water usage DOE tests against, this electric tank uses 1,219 kWh a year. That is 87 kWh below the class median of 1,306 kWh, and it ranks 14th lowest of 194 models.


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.

This model: 1,219 kWh

What these figures mean

The figure of 1,219 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 4.07 with the DOE test's daily hot-water draw for the high draw pattern. It is therefore a test-condition value, and a household whose real hot-water use differs will see a different result. The source is DOE CCD, retrieved 2026-09-19. The class median of 1,306 kWh covers the 194 models registered as an electric tank at the high draw pattern. This model sits 87 kWh below that median, 14th lowest of 194, in the lowest quarter of its class. The calculation is described in how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. That is the only condition under which the 1,219 kWh figure and the class rank of 14th apply. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 87 gallons, with a rated volume of 72 gallons. Whether those values cover a particular household's busiest hour cannot be decided from registry data. A household with lighter use falls under a different draw pattern, so the 1,306 kWh median does not describe it. Those readers can compare by fuel, space and size with the water heater selector.

The running cost is not written on this page, because it depends on the electricity tariff you pay. The registry has no rate, and this page does not assume one. To check the cost yourself, multiply 1,219 kWh by your own price per kilowatt-hour; the result holds only at the high draw pattern and the test's daily draw. The cost calculator does this for your own ZIP. The installed price range is shown in its own block with its source and date, as a modeled range and not a quote. If you are replacing a unit and only have its model number, find a same-class replacement to compare against the class median of 1,306 kWh.
