RHEEM/RUUD PROE40 M2 RH95

This site computes the 3,493 kWh figure; the registry does not list 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. This model's UEF is 0.93. The inputs come from the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The figure holds only at the federal test's daily draw. A household drawing more or less hot water will use a different amount. The class median of 3,531 kWh comes from the 426 models registered as an electric tank at the medium draw pattern. The calculation steps are set out in how the annual energy and cost figures are calculated.

The medium draw pattern stands for a typical household's hot-water use, including a busy morning. For that use, this model lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 55 gallons. Its rated volume is 36 gallons. A plumber or seller checking a like-for-like swap can match these two values against the unit being replaced. To find other units in the same class, use the same-class replacement search by model number. If a household's morning demand is above 55 gallons, its use differs from what the medium pattern describes. For that household, the 3,493 kWh figure and the class rank do not apply as stated.

This page does not state a running cost, because it depends on your own utility's electricity tariff. The page instead computes it from your ZIP, starting from 3,493 kWh a year at the medium draw. The 38 kWh gap to the class median works the same way: its cost depends on your rate. To convert both figures, enter your ZIP in 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 installed-cost range, not a quote from an installer. The registry data does not include what an installer would charge for this specific unit at your address.
