U.S. CRAFTMASTER 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).
If you are checking the U.S. CRAFTMASTER GCBL-40 4**, this gas tank water heater uses 194 therms of natural gas a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It is 9 therms above the 185 therms median of the 288 gas tank models registered at that draw pattern.
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.

The 194 therms figure is calculated by this site; the registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium draw pattern. This model's UEF is 0.57, from the DOE CCD as retrieved on 2026-09-19. There are 288 gas tank models at the medium draw pattern. Ranked from lowest energy use, this model is 278th. A household that draws more or less hot water than the test assumes will use a different amount of gas. The method behind the annual figure shows each step of that calculation.
The model has a rated volume of 38 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 68 gallons. These ratings place it in the medium draw pattern, which DOE uses to represent typical household hot-water use. For a reader comparing energy use, its position of 278th out of 288 matters. It means most gas tank models tested at the same draw pattern use less gas than this one. To look at same-class models with lower energy use, find a same-class replacement by model number. The selector by fuel, space and size widens the search beyond this class.
This page does not state a running cost in the text. The yearly cost of 194 therms depends on your state's average residential gas price, so the page calculates it from your ZIP. The cost calculator for your own ZIP applies that price to the same medium draw pattern figure. The gap to the 185 therms class median is 9 therms a year, so any cost difference against the median also depends on your price. No installed price range is published for this model. Its ratings lie outside the range that the cost database's model was fitted on, and that range is not stretched past it. What installation would cost for this unit is therefore unknown.
