FRIEDRICH PROG40-40N RH67 PDV
0.63 UEF DOE CCD · 2026-09-19Grade E: 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 checking this FRIEDRICH PROG40-40N RH67 PDV, a gas tank water heater: it uses 176 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 9 therms below the class median of 185 therms, and it ranks 62nd lowest of 288 models.
Energy use per year
176 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 below the median of 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 62 of 288, lowest energy first.
Solid line: this model (176 therms). Dashed line: the class median.

The figure of 176 therms is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.63 with the DOE test's daily hot-water draw for the medium draw pattern. It applies to natural gas at that test draw only and does not measure any particular home. The source is DOE CCD, retrieved 2026-09-19. The class is the 288 models registered as a gas tank at the medium draw pattern. Its median is 185 therms, so this model sits 9 therms below it. At 62nd lowest of 288, it is in the lowest quarter of its class for energy use. The methodology for the annual cost calculation describes the steps.
The medium draw pattern describes a typical three- or four-person household with a busy morning, so the figure fits a home that uses hot water at about that level. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 67 gallons. The rated volume is 38 gallons. A household that draws noticeably more or less than the test does would use a different amount of gas than 176 therms. This page has no annual energy figure for other draw patterns, so that difference is not available here. Whether 67 gallons covers a specific household's peak hour is also not shown by the data. The water heater selector by fuel, space and size filters models by those limits.
The running cost is not written in the text because it depends on your state average residential gas price. Multiplying 176 therms by the price you pay per therm gives the yearly gas cost at the medium draw pattern. The cost calculator on your own ZIP does this with your state's average price. The installed price range appears in its own block on this page, with its source and date. It is a modeled installed-cost range, not a quote, and it is not repeated here. If you are comparing this PROG40-40N RH67 PDV with another unit, find a same-class replacement by model number to compare models registered in the same class, with the class median of 185 therms as the reference.
