Ruud PROPH50 T2 RH375-SO
3.88 UEF DOE CCD · 2026-09-19Grade A: 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 Ruud PROPH50 T2 RH375-SO, this electric tank water heater uses 837 kWh of electricity a year. That figure applies at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,694 kWh below its class median of 3,531 kWh, ranking 5th lowest of 426 models.
Energy use per year
837 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 5 of 426, lowest energy first.
Solid line: this model (837 kWh). Dashed line: the class median.

UEF 3.88 · Grade A Price it on your ZIP
The registry does not print the 837 kWh figure. This site calculated it from the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the medium draw pattern. The registry lists this model's UEF as 3.88. Both inputs come from the DOE Compliance Certification Database, retrieved 2026-09-19. The figure applies only at that test draw. A household that draws more hot water each day uses more electricity than the figure shows. A household that draws less uses less. This page has no data on how far real use differs from the test draw. The full calculation is set out in how the annual energy and cost figures are calculated.
The class comparison in the summary covers only the 426 models registered as an electric tank at the medium draw pattern. It is most useful for a household whose daily hot-water use is close to that pattern. The registry lists this model's rated volume as 45 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 67 gallons. If a household needs more than 67 gallons in its busiest hour, this rating does not cover that peak. The 5th ranking also says nothing about models tested at other draw patterns or on other fuels. To look at those classes, use the water heater selector by fuel, space and size.
This text does not give a running cost because it depends on your own electricity tariff. The page multiplies 837 kWh by the rate for your ZIP, and the result holds only at the medium draw pattern. Two readers with the same model but different utility rates will see different running costs. The installed price has its own block, with its source and date. It is a modeled range, not a quote. To see this model's running cost on your own rate, use the cost calculator for your ZIP. To find another model among the 426 in the same class, use the same-class replacement search by model number.
