FRIEDRICH SCG40T03ST34U1
0.59 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 checking the FRIEDRICH SCG40T03ST34U1, its annual energy use is 188 therms of natural gas. That figure applies to the medium draw pattern, the standard daily hot-water usage DOE tests against. It is 3 therms above the class median of 185 therms across 288 gas tank models.
Energy use per year
188 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 186 of 288, lowest energy first.
Solid line: this model (188 therms). Dashed line: the class median.

The 188 therms figure is calculated by this site, not listed in the registry. It starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.59 for this model. That ratio is applied to the federal test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. The result 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. This model ranks 186th lowest for energy use among 288 models. That places it in the second-highest quarter of its class for energy use.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 67 gallons for this model. The rated volume is 38 gallons. The medium draw pattern describes a typical three- or four-person household on a busy morning. The 188 therms figure applies most directly to a household of that kind. This model uses 3 therms more than the 185 therms median. A reader ranking units by gas use alone will find models ahead of it in the class. For a household with a different daily use, this page has no figure. To compare by fuel, space and size, use the water heater selector by fuel, space and size. To find a same-class unit by model number, use the same-class replacement search by model number.
The running cost depends on the average residential gas price in your state, so this text does not state one. The cost calculator on your own ZIP works it out using the 188 therms figure. The method is described in how the annual cost is calculated. A modeled installed-cost range appears in its own block on this page, with its source and date. It is a modeled range, not a quote. The gap from the class median is 3 therms. That is the whole difference in annual energy between this model and a median unit at the test's draw. Your cost for that gap depends on the same gas price. The figure is a test-condition value, not a measurement in your home, and actual gas use in a home is not available in this data.
