FRIEDRICH PRO H50 T2 RH310BM

3.5 UEF DOE CCD · 2026-09-19
B

Grade 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).

You are verifying one model's test figure. FRIEDRICH PRO H50 T2 RH310BM uses 928 kWh of electricity a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,603 kWh below the class median of 3,531 kWh.

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.

What these figures mean

The registry lists a UEF, the ratio of hot water delivered to energy used, of 3.5 for this model. This site computes the annual figure itself. It combines that UEF with the DOE test's daily hot-water draw for the medium draw pattern. The registry does not publish the annual figure. The source data is DOE CCD, retrieved 2026-09-19. Among 426 electric tank models at the medium draw pattern, this model has the 84th lowest energy use. That places it in the lowest quarter of its class, whose median is 3,531 kWh. The method for the annual calculation is documented separately.

This figure suits a household that matches the medium draw pattern, a typical household on a busy morning. For supply, the registry gives a first hour rating, the gallons of hot water available in the first hour from a full tank. The value is 67 gallons, and the rated volume is 45 gallons. Neither value measures energy use. A household with much heavier or lighter daily use than the medium draw pattern is not covered by 928 kWh. Energy use at other draw patterns is not available here, and it is not estimated. To compare supply and space, use the water heater selector by fuel, space and size.

The running cost is not stated in the text, because it depends on your own utility electricity tariff. Multiply 928 kWh by your rate per kilowatt-hour to get a yearly cost at the medium draw pattern. The cost calculator on your ZIP does this with your local rate. The gap to the class median is 2,603 kWh a year, and its cost scales with your tariff. Actual use in your home may differ from the test's daily hot-water draw. The installed price range appears in its own block, as a modeled range and not a quote. To compare other units of this class, use the same-class replacement lookup by model number.
