FRIEDRICH PROPH50 T0 RH120
3 UEF DOE CCD · 2026-09-19Grade C: 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 checking the FRIEDRICH PROPH50 T0 RH120, this electric tank uses 1,083 kWh of electricity a year. That figure applies at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,448 kWh below the 3,531 kWh median of the 426 electric tanks registered at that pattern.
Energy use per year
1,083 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 116 of 426, lowest energy first.
Solid line: this model (1,083 kWh). Dashed line: the class median.

UEF 3 · Grade C Price it on your ZIP
This site calculated the 1,083 kWh figure. It does not come directly from the registry. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, and the daily hot-water draw that the DOE test sets for the medium pattern. This model's UEF is 3. Both inputs come from the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The figure holds only at that test draw. A household that uses more or less hot water each day will use a different amount of electricity, and that amount is not available here. The steps of the calculation are explained on the page about how the annual cost is calculated.
DOE uses the medium pattern to represent a typical household's daily hot-water use. The comparison therefore applies to homes whose use is close to that test. At that pattern, this model has the 116th lowest energy use of 426 registered electric tanks. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 51 gallons. Its rated volume is 46 gallons. A plumber or seller checking a match can compare these two values with the unit already in place. Other models in the same class and draw pattern can be listed with the same-class replacement search by model number.
The 2,448 kWh gap to the class median is measured only at the medium test draw. It may not describe a household whose daily hot-water use is well above or below that pattern. This data has no energy figure for this model at any other draw pattern. The running cost is not given in this text. It depends on your own utility's electricity tariff. The page calculates it from your ZIP, and the cost calculator for your own ZIP applies the same method. The installed price range appears in a separate block with its own source and date. It is a modeled range, not a quote.
