Rheem PROG50-38N RH60 *
0.64 UEF DOE CCD · 2026-09-19Grade G: 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 Rheem PROG50-38N RH60 *, this gas tank water heater uses 264 therms of natural gas a year. That figure applies to the high draw pattern, the standard daily hot-water usage DOE tests against. It is 4 therms above the 260 therms median of the 414 gas tank models registered at that draw pattern.
Energy use per year
264 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 above the median of 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 236 of 414, lowest energy first.
Solid line: this model (264 therms). Dashed line: the class median.

The registry does not list the 264 therms figure. This site calculated it from the registry's UEF, the ratio of hot water delivered to energy used. The calculation also uses the daily hot-water draw set by the DOE test for the high draw pattern. At that test draw, this model's UEF is 0.64. The source is the DOE Compliance Certification Database, retrieved 2026-09-19. The result reflects the test's fixed daily draw, not a measurement from a real home. A home that uses more or less hot water than the test would use a different amount of gas, and this page does not have that figure. The full steps are on the page explaining how the annual energy and cost figures are calculated.
The high draw pattern represents a larger household, or one where showers and laundry happen at the same time. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 85 gallons. That comes from a rated volume of 48 gallons. Among the 414 gas tank models at the high draw pattern, it ranks 236th for lowest energy use. These figures do not describe a home that uses less hot water than the test assumes. The registry does not record household use. So whether the first hour rating covers a particular home's busiest hour is not known from this data. To compare other fuels or sizes, use the water heater selector by fuel, space and size.
This text does not give a running cost because residential gas prices vary by state. The cost block works it out from your ZIP. It applies your state's average residential natural gas price to the 264 therms test-draw figure. Cost rises in step with energy use at any given rate. So the 4 therms gap above the class median carries into the cost in the same proportion. This page cannot see your own bill rate if it differs from the state average. You can enter your ZIP in the running cost calculator for your ZIP. The installed price range shown in its own block elsewhere on this page is a modeled range, not a quote. That block gives its own source and date.
