Ruud PRO+G40-38U RH67 PD*
0.64 UEF DOE CCD · 2026-09-19Grade E: where this UEF sits among the 288 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are checking the Ruud PRO+G40-38U RH67 PD* gas tank water heater, it uses 173 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 12 therms below the 185 therms median for the 288 gas tank models registered at the same draw pattern.
Energy use per year
173 therms 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 natural gas rate where you live.
That is below the median of 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 44 of 288, lowest energy first.
Solid line: this model (173 therms). Dashed line: the class median.

This site calculated the 173 therms figure. The registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw the DOE test sets for the medium pattern. For this model the UEF is 0.64. The DOE registry record behind the figure was retrieved on 2026-09-19. Among the 288 gas tank models at the medium draw pattern, this one ranks 44th lowest for energy use. That puts it in the lowest quarter of its class. The figure applies only at the test's daily draw. A household that uses more or less hot water will burn a different amount of gas, and this data does not show how much. The method behind the annual figure explains each step.
The medium pattern stands for a typical household of several people on a busy morning. This tank has a rated volume of 38 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 peak hour stays within 67 gallons matches the conditions the rating was tested under. A home whose busiest hour needs more is outside what this rating covers. The 173 therms figure is for natural gas, so it does not describe running costs in a home without a gas supply. To compare other units by fuel, space and size, use the water heater selector by fuel and size. To check units in the same class, use the same-class replacement search by model number.
The page text does not state a yearly running cost. The cost of 173 therms depends on the average residential gas price in your state. For that reason the page works it out from your ZIP. The 12 therms gap to the class median also depends on that rate for its value in money. Two readers in different states will see different costs for the same unit. You can enter your own ZIP in the running cost calculator. The installed price range sits in its own block, with its source and date. It is a modeled range, not a quote. This data does not show maintenance costs or how the unit performs outside the DOE test.
