Ruud PRO+G50-40N RH67 PD
0.69 UEF DOE CCD · 2026-09-19Grade F: where this UEF sits among the 414 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are checking the Ruud PRO+G50-40N RH67 PD, it uses 245 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 15 therms below the 260 therms median of the 414 gas tank models registered at the high draw pattern.
Energy use per year
245 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 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 130 of 414, lowest energy first.
Solid line: this model (245 therms). Dashed line: the class median.

The 245 therms figure is computed by this site, not by the registry. It combines the model's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. The registry lists a UEF of 0.69 for this unit, from DOE CCD data retrieved 2026-09-19. Ranked by energy use, the model is 130th lowest of 414 in its class. That places it in the second-lowest quarter of its class for energy use. The page on how the annual energy and cost figures are calculated sets out each step of that calculation.
The high draw pattern describes a larger household, or one where showers and laundry overlap. The 245 therms figure applies at that level of use only. Its rated volume is 48 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 79 gallons. The figure does not describe a household that draws less hot water than the DOE test assumes. Energy use at other draw levels is not available on this page. To compare against other gas tank models at the high draw pattern, use the same-class replacement finder by model number. For a different fuel or space, the water heater selector by fuel, space and size covers other classes.
The text of this page gives no running cost. The cost of 245 therms of natural gas depends on your state's average residential gas price. For that reason, the page works it out from your ZIP. The running cost calculator for your own ZIP applies that rate to this model's figure. The gap of 15 therms below the 260 therms class median holds at the high draw pattern's test usage only. The installed-cost range shown in its own block is a modeled range with its source and date, not a quote. The registry does not give energy use at your household's actual hot-water draw, so it is unknown here.
