Rheem PROE55 T2 RH94

The 3,531 kWh figure does not come from the registry. This site calculated it from two inputs. The first is the model's UEF, the ratio of hot water delivered to energy used, which the registry lists as 0.92. The second is the DOE test's daily hot-water draw for the medium draw pattern. The UEF comes from the DOE Compliance Certification Database, retrieved 2026-09-19. The medium pattern represents a typical household on the federal test day, not any specific home. If your household uses more or less hot water than the test assumes, your yearly use will differ from 3,531 kWh. The data here cannot show by how much. The calculation steps are set out in how the annual cost is calculated.

The 3,531 kWh figure applies only at the medium draw pattern. The tank's rated volume is 55 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 72 gallons. A household whose busiest hour stays within that first hour rating is close to the conditions behind the figure. A household with heavier mornings falls outside the test pattern. The registry gives no energy figure for that case, so it is not available here. To compare units of other sizes or fuels, use the selector by fuel, space and size.

In its class, this model ranks 213th lowest in energy use out of 426. Its difference from the class median is 0 kWh. At the medium draw pattern, it therefore uses the same amount of energy as the class median. The running cost is not given here because it depends on your own utility's electricity rate. Enter your ZIP in the cost calculator for your own ZIP to see it. The installed price range has its own block, with its source and date. That range is modeled, not a quote. To find a unit in the same class by model number, use the same-class replacement lookup.
