Ruud PROE40 T2 RH CG
0.92 UEF DOE CCD · 2026-09-19Grade G: 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).
Checking the Ruud PROE40 T2 RH CG? This electric tank uses 3,531 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That equals its class median of 3,531 kWh, a difference of 0 kWh. It ranks 213th lowest in energy use of 426 models.
Energy use per year
3,531 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 equal to the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 213 of 426, lowest energy first.
Solid line: this model (3,531 kWh). Dashed line: the class median.

The registry does not print the 3,531 kWh figure. This site computes it from two inputs. The first is the model's UEF, the ratio of hot water delivered to energy used, which is 0.92. The second is the DOE test's daily hot-water draw for the medium pattern. Both registry values come from the DOE CCD, retrieved 2026-09-19. The medium pattern stands for a typical household's daily use, including a busy morning. The annual figure applies only at that test draw. A home that draws more or less hot water each day will use a different amount, and that amount is not available here. The page on how the annual energy and cost figures are calculated explains each step of the method.
This unit is compared with the 426 models registered as an electric tank at the medium draw pattern. It sits at the class median given above. Its rank of 213th places it in the second-lowest quarter of its class for energy use. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 55 gallons. Its rated volume is 36 gallons. These two values describe the delivery the medium test assumes. A household whose busiest hour needs more than 55 gallons falls outside what this rating covers. To check another unit against the same class, use the tool to find a same-class replacement by model number.
The text on this page does not give a running cost. The cost of 3,531 kWh a year depends on your own utility's electricity tariff, and this page does not know that rate. The running-cost calculator for your ZIP code multiplies that annual energy by your local rate. That result still assumes the medium draw pattern described above. The installed price range appears in its own block on this page, with its source and date. It is a modeled installed-cost range, not a quote from an installer. A plumber or seller checking a listing can compare these values with the PROE40 T2 RH CG entry in the DOE CCD.
