AMERICAN GCBL-40 4**
0.57 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).
Checking the AMERICAN GCBL-40 4**? This gas tank uses 194 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 9 therms above the class median of 185 therms, ranking 278th lowest of 288 models.
Energy use per year
194 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 278 of 288, lowest energy first.
Solid line: this model (194 therms). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's UEF lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

UEF 0.57 · Grade G Price it on your ZIP
The figure of 194 therms is calculated by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.57 with the federal test's daily hot-water draw for the medium draw pattern. That pattern represents a typical three- or four-person household. The source data is the DOE CCD, retrieved 2026-09-19. A household with a different daily draw would use a different amount, and this page does not estimate it. The method behind the annual figure is documented separately.
The comparison group is the 288 models registered as a gas tank at the medium draw pattern. This unit sits 9 therms above the class median of 185 therms, and its rank of 278th lowest energy use places it in the highest quarter of its class for energy use. The ratings are a first hour rating, the gallons of hot water available in the first hour from a full tank, of 68 and a rated volume of 38 gallons. Those describe capacity, and this page does not rank them against the class. The figure fits a household near the medium draw pattern. It does not describe a much larger or smaller daily draw. Anyone who wants lower energy use in the same class can 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 for the reader's ZIP. The cost calculator on your own ZIP applies that price to the 194 therms shown for this model. An installed price range is not published. This model's ratings, including its UEF of 0.57 and rated volume of 38 gallons, lie outside the range the cost database's model was fitted on, and the range is not stretched past it. To compare other units by fuel, space and size, the water heater selector is available.
