FRIEDRICH PROG40-38U RH62 EC1*
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).
Verifying the FRIEDRICH PROG40-38U RH62 EC1*? 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. It ranks 231st lowest energy use of 288 models.
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.

UEF 0.58 · Grade G Price it on your ZIP
The figure of 191 therms belongs to the medium draw pattern at the federal test's daily hot-water draw. The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.58. This site computed the annual figure from that UEF and the DOE test's daily draw, so the registry does not state it directly. The data source is DOE CCD, retrieved 2026-09-19. The class median is 185 therms, and this model sits 6 therms above it. Its rank is 231st lowest energy use of 288, in the highest quarter of its class for energy use.
A household whose use resembles the medium draw pattern can compare its own gas bills against 191 therms. A household that uses more or less hot water will see a different annual figure, and this page does not estimate it. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 71 gallons. The rated volume is 38 gallons. Those two values describe capacity, not energy use, so they do not change the rank of 231st among 288. To compare models within the same class, find a same-class replacement by model number.
The running cost is not stated here because it depends on the state average residential gas price. Enter your ZIP in the cost calculator for your own ZIP to apply your rate to 191 therms. The result stays tied to the medium draw pattern. At any single rate, this model costs more to run than the class median of 185 therms, in proportion to the 6 therms difference. The method behind the annual cost explains each step. If your fuel, space or size differ, the water heater selector by fuel, space and size covers those inputs.
