AMERICAN GCR-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).
For a second opinion, AMERICAN GCR-30R 4** uses 185 therms of natural gas a year. That figure is for the medium draw pattern, the standard daily hot-water usage DOE tests against. It equals the class median of 185 therms, a difference of 0 therms, among 288 gas tank models.
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.

UEF 0.6 · Grade F Price it on your ZIP
This site computed the figure of 185 therms; the registry does not publish it. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used. This model's UEF is 0.6. It is applied to the daily hot-water draw in the DOE test for the medium draw pattern. That pattern stands for a typical household on a busy morning. The fuel is natural gas, and the source is the DOE CCD, retrieved 2026-09-19. A household that draws more or less hot water than the test will use a different amount. This page does not estimate that difference.
Its rank is 89th lowest energy use of 288, which places it in the second-lowest quarter of its class. The difference from the class median of 185 therms is 0 therms. So the data shows this unit using the same annual energy as the class median. It suits a reader who wants to confirm a figure near that median. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons. The rated volume is 29 gallons. A household whose busiest hour needs more than 62 gallons is outside what this rating covers.
The running cost is not stated in this text. It depends on your state's average residential gas price, which this page cannot know. The cost calculator applies the price for your ZIP to 185 therms. The steps are set out in how the annual cost is calculated. An installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it. To compare against another unit, find a same-class replacement by model number and check its figure at the same draw pattern.
