STATE FMDV-30 2**
0.61 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 STATE FMDV-30 2**, this site computes 182 therms of natural gas a year for it. That figure applies to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 3 therms below the 185 therms median of the 288 gas tank models in that class.
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.
Solid line: this model (182 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 182 therms figure does not come from the registry itself. This site computed it from two inputs. The first is the registry's UEF, the ratio of hot water delivered to energy used. The second is the DOE test's daily hot-water draw for the medium pattern. The registry lists this model's UEF as 0.61. The medium pattern represents a typical household's daily use, as DOE defines it for testing. If your household draws more or less hot water than that test day, your gas use will differ from 182 therms. This page does not estimate how large that difference is. The inputs come from the DOE Compliance Certification Database, retrieved 2026-09-19. The steps are set out in how this site calculates annual energy and cost.
This model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 60 gallons. Its rated volume is 29 gallons. It matches a home whose busiest hour needs no more than 60 gallons of hot water. It does not match a home whose peak hour needs more than 60 gallons, or a home without a natural gas supply. For those homes, the 182 therms figure does not describe real use, and a different class may apply. To compare other fuels, spaces and sizes, use the water heater selector by fuel, space and size. If you are checking a swap, you can look up a same-class replacement by model number.
Among the 288 models registered as a gas tank at the medium draw pattern, this one ranks 73rd lowest for energy use. That places it in the second-lowest quarter of its class. The ranking uses the test draw, and this page has no class comparison at other daily volumes. The running cost is not given in this text because it depends on your state's average residential gas price. The page calculates it from your ZIP, or you can enter one in the cost calculator on 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 this page does not stretch that range. The installed price therefore remains unknown on this page.
