U.S. CRAFTMASTER GCBL-30R 4**
0.6 UEF DOE CCD · 2026-09-19Grade F: 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-30R 4**, it uses 185 therms of natural gas a year. That figure is for a gas tank at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 0 therms from the class median of 185 therms and ranks 89th lowest energy use of 288.
Energy use per year
185 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 equal to the median of 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 89 of 288, lowest energy first.
Solid line: this model (185 therms). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's rated tank size 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 185 therms figure comes from this site's calculation, not from the registry. 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 0.6, taken from the DOE CCD record retrieved 2026-09-19. The class median is also 185 therms, so the gap of 0 therms places this unit at the median of the 288 gas tank models registered at the medium draw pattern. Its rank of 89th lowest energy use is counted within that same group. The steps behind the annual figure are set out in how the annual cost is calculated.
The 185 therms figure applies to a household whose hot-water use is close to the medium draw pattern. This site describes that pattern as a typical household with a busy morning. The unit has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 65 gallons. Its rated volume is 29 gallons. For a household that draws well beyond the medium pattern, the 185 therms figure does not describe its use. This page has no energy figure for other draw levels, so that value is not available here. To compare other units, use the water heater selector by fuel, space and size.
The running cost is not stated in this text. It depends on your state's average residential gas price, so the page computes it from your ZIP code and the 185 therms figure. The cost calculator on your own ZIP shows that result. An installed price range is not available for this model. Its ratings lie outside the range the cost database's model was fitted on, and the page does not stretch that range past it. If you are checking a unit against others in its class of 288 models, you can find a same-class replacement by model number.
