Rheem PRO H50 T2 RH310BM
3.5 UEF DOE CCD · 2026-09-19Grade B: where this UEF sits among the 426 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are verifying the Rheem PRO H50 T2 RH310BM, it uses 928 kWh of electricity a year. That figure holds at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,603 kWh below the 3,531 kWh median of the 426 electric tank models registered at that pattern.
Energy use per year
928 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 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 84 of 426, lowest energy first.
Solid line: this model (928 kWh). Dashed line: the class median.

UEF 3.5 · Grade B Price it on your ZIP
The 928 kWh figure is computed by this site, not taken from the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily draw for the medium pattern. For this model the UEF is 3.5, read from DOE's Compliance Certification Database on 2026-09-19. The result applies only at that test draw; a household drawing more or less hot water each day will use a different amount. Among the 426 comparable models, this one ranks 84th lowest in energy use, which places it in the lowest quarter of its class. The method behind this figure and the cost step is set out in how the annual cost is calculated.
The medium draw pattern describes a typical mid-sized household's daily hot-water use, so the 928 kWh figure fits homes close to that usage. Capacity is a separate check from energy use, and it rests on two registry figures. This tank has a rated volume of 45 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 67 gallons. A home whose busiest hour needs more than 67 gallons falls outside what that rating covers. The 2,603 kWh gap to the median is measured at the test draw, so it may not hold for homes with very different use. Other models can be compared in the water heater selector by fuel, space and size.
The running cost is not stated in this text, because it depends on your own utility's electricity tariff. The page computes it from your ZIP instead, and the same step can be repeated in the cost calculator for your own ZIP. The 2,603 kWh gap to the class median is also measured in electricity, so its cost depends on that same tariff. The installed price shown in its own block is a modeled installed-cost range with its source and date, not a quote. To compare another electric tank at the medium draw pattern, find a same-class replacement by model number.
