Rheem PROG40S-40N RH62
0.58 UEF DOE CCD · 2026-09-19Grade G: 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 verifying the Rheem PROG40S-40N RH62, it uses 191 therms of natural gas a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 6 therms above the 185 therms median of the 288 gas tank models registered at that draw pattern.
Energy use per year
191 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 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 231 of 288, lowest energy first.
Solid line: this model (191 therms). Dashed line: the class median.

This site computed the 191 therms figure; the registry does not publish it. The figure 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 medium draw pattern. The registry lists the UEF of the PROG40S-40N RH62 as 0.58 in the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The figure holds only at that test draw. A household that uses more or less hot water than the test will use a different amount of gas. The registry lists a rated volume of 39 gallons. It also lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 66 gallons. The method is explained on how the annual cost is calculated.
The class used here contains the 288 models registered as a gas tank at the medium draw pattern. Within that class, the PROG40S-40N RH62 ranks 231st for lowest energy use of 288. That places it in the highest quarter of its class for energy use. At the test draw, it uses 6 therms a year more than the 185 therms class median. The figure applies most directly to a household whose hot-water use is close to the medium draw pattern. A reader looking for lower energy use at the same class can check a same-class replacement by model number. A reader open to another fuel or tank size can use the selector by fuel, space and size. The registry data covers rated energy use only. It says nothing about service life or repairs.
The text of this page does not state a running cost. The cost of 191 therms a year depends on the average residential natural gas price in the reader's state. The page calculates that cost from the reader's ZIP code, and the cost calculator on your own ZIP runs the same calculation. That result still assumes the medium draw pattern at the federal test's daily draw. A real gas bill can also include space heating, cooking and hot-water use that differs from the test. The installed price range is shown in its own block, with its source and date. It is a modeled installed-cost range, not a quote. The registry does not say what this model costs to run in a specific home at that home's actual hot-water use.
