FRIEDRICH PROG40S-38N 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).
Checking this model's energy use: it uses 191 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 6 therms above the class median of 185 therms among 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.

The FRIEDRICH PROG40S-38N RH62 is registered with a UEF, the ratio of hot water delivered to energy used, of 0.58. The registry does not list annual energy. This site computes 191 therms from that UEF and the DOE test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure describes the test's draw, not a measurement of any particular home. A household that uses more or less hot water than the medium draw pattern will use a different amount of natural gas, and this page does not estimate that difference.
In its class of 288 gas tank models at the medium draw pattern, this model ranks 231st lowest energy use. That places it in the highest quarter of its class for energy use. Its 191 therms is 6 therms above the class median of 185 therms. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 65 gallons, and the rated volume is 39 gallons. The figure suits a reader confirming that a listing matches the registry for a household near the medium draw pattern. It does not suit a reader who needs a model at or below the class median. A household with heavier demand can compare its own peak use with that rating; this page does not say whether a given household is covered.
The running cost is not written here because it depends on the state average residential gas price, which differs by location. The cost calculator takes a ZIP and applies that price to the 191 therms shown above. The method for the annual cost sets out how the calculation works. The result holds only at the medium draw pattern, so a different hot-water use changes it. The modeled installed-cost range appears in its own block with its source and date, as a range and not a quote. To compare models against the class median of 185 therms, the same-class replacement search by model number finds other registered options.
