AMERICAN FMDV-30 2**

0.61 UEF DOE CCD · 2026-09-19
F

Grade 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 this listing, the AMERICAN FMDV-30 2** uses 182 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 3 therms below the class median of 185 therms. It ranks 73rd lowest of 288 gas tank models.


Energy use per year

182 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 below the median of 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 73 of 288, lowest energy first.

This model: 182 therms

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.

What these figures mean

The figure of 182 therms was computed by this site, not by the registry. It uses the registry's UEF and the daily hot-water draw that the DOE test assigns to the medium draw pattern. The UEF, the ratio of hot water delivered to energy used, is 0.61 for this model. The source is the DOE CCD, retrieved 2026-09-19. The class median is 185 therms, and this model sits 3 therms below it. The class is the 288 models registered as a gas tank at the medium draw pattern. That places the model in the lower half of its class for energy use, at 73rd lowest.

The figure is most relevant to a household whose hot-water use matches the medium draw pattern. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 60 gallons. The rated volume is 29 gallons. The 182 therms figure applies only at that draw. A household that uses more or less hot water than the test assumes will use a different amount of gas. This page has no figure for other draw patterns. To compare units by fuel, space and size, use the water heater selector. To look for a same-class unit by model number, use the replacement finder.

The running cost is not stated here because it depends on your own rate. It is 182 therms of natural gas multiplied by the state average residential gas price. The cost calculator applies that price from your ZIP. The page on how the annual cost is calculated describes the method. The installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on. That range is not stretched past its limit, so no installed price is estimated. The 182 therms figure also assumes the medium draw pattern and cannot show actual use in one home.
