AMERICAN G6-UT3030NVR 5**
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 AMERICAN G6-UT3030NVR 5**, it uses 185 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That equals the 185 therms median of the 288 gas tank models at the same draw pattern. It ranks 89th lowest of 288 for energy use.
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 was computed by this site, not by 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. The registry lists a UEF of 0.6 for this model. The source is the DOE Compliance Certification Database, retrieved 2026-09-19. The figure holds at the federal test's draw, not at any particular household's use. A home that draws more hot water than the test will use more gas than 185 therms, and a home that draws less will use less. How far real use departs from the test is not available here. The steps behind the calculation are set out in how the annual cost is calculated.
Within its class, the AMERICAN G6-UT3030NVR 5** sits at the median for energy use. Its 185 therms is 0 therms away from the 185 therms class median. It still ranks 89th lowest of 288 and falls in the second-lowest quarter of its class. The data does not say how many models share the 185 therms figure. The class covers only gas tank models at the medium draw pattern, so this comparison says nothing about other heater types. The medium pattern stands for a typical household's use on a busy morning. For that use, the registry lists a rated volume of 29 gallons. It also lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 67 gallons.
A household that draws more hot water than the medium pattern falls outside the condition behind these figures. For that household, the 185 therms estimate does not describe the unit's gas use. To compare other units by fuel, space and size, use the water heater selector. This page gives no running cost in its text. The cost depends on your state's average residential gas price, so the page computes it from your ZIP in the cost calculator for your own ZIP. 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.
