FRIEDRICH PROG40-38N 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).
The FRIEDRICH PROG40-38N RH62 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. It ranks 231st lowest in energy use among 288 gas tank models.

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 191 therms figure belongs to the medium draw pattern, which describes a typical family household with a busy morning of hot-water use. This site computed the figure from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.58 for this model. It combined that UEF with the test's daily draw. The registry does not publish this annual figure itself. The source is DOE CCD, retrieved 2026-09-19. The figure applies only to that draw. A household that uses more or less hot water will burn a different amount of gas.
Against the class median of 185 therms, this model sits 6 therms higher. Its rank of 231st lowest of 288 places it in the highest quarter of its class for energy use. Higher energy use at the same draw means more gas burned for the same hot water. The comparison covers only models registered as a gas tank at the medium draw pattern. It says nothing about other fuels or other draw patterns. Readers who want a unit with lower gas use can start from a same-class replacement by model number. Readers who prefer to filter by fuel, space and size can use the water heater selector.
The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 64 gallons. The rated volume is 38 gallons. These two values describe hot-water supply, not gas use, so they do not change the 191 therms figure. Households that draw more than the medium draw pattern should compare them with their own peak demand. The running cost is not stated here. It depends on the state average residential gas price, which varies by location. To compute it for your own ZIP, use the cost calculator. The calculation method explains how the annual cost is built from therms and price.
