AMERICAN GCF-40 1**
0.64 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 the AMERICAN GCF-40 1**, a gas tank water heater, it uses 173 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 12 therms below the 185 therms median of the 288 gas tank models registered at that draw pattern.
Energy use per year
173 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 44 of 288, lowest energy first.
Solid line: this model (173 therms). Dashed line: the class median.

The figure of 173 therms is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.64 for this model, and from the DOE test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. Among the 288 gas tank models at this draw pattern, the model has the 44th lowest energy use, which places it in the lowest quarter of its class. The gap to the 185 therms median is 12 therms. The methodology page explains how the annual figures are calculated.
The figure describes a household that matches the medium draw pattern, meaning a typical three- or four-person household on a busy morning. For that household, 173 therms is the test-based annual use of the AMERICAN GCF-40 1**. It does not describe a household with a different daily use, and this page has no annual figure for other draw patterns. The tank's first hour rating, the gallons of hot water available in the first hour from a full tank, is 70, and its rated volume is 38. Whether those values fit a given home depends on that home's peak demand, which this page cannot measure. The water heater selector filters by fuel, space and size.
The running cost is not written in the text because it depends on your state's average residential gas price. The 173 therms figure is natural gas use at the medium draw pattern, so the cost follows from applying your own rate to it. The cost calculator does this from your ZIP. The 12 therms difference from the class median of 185 therms also becomes a cost only at your rate, and this page states no cost difference. Actual use in a home may differ from the test draw, and how much is not available here. The modeled installed-cost range appears in its own block, with its source and date.
