U.S. CRAFTMASTER FMHR-30 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).
The U.S. CRAFTMASTER FMHR-30 4** gas tank heater you are verifying uses 185 therms of natural gas a year. That figure applies at the medium draw pattern, the standard daily hot-water usage DOE tests against. It equals the class median of 185 therms and ranks 89th for lowest energy use among 288 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.

The 185 therms figure is calculated by this site. The registry does not publish it. It combines the model's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw. This model's UEF is 0.6, taken from the DOE CCD and retrieved 2026-09-19. The figure assumes the test's daily draw, so a household using more or less hot water will use a different amount of gas. The registry data does not show how large that difference would be. The 0 therms difference from the class median also applies only under the test condition. The page on how the annual figure is calculated lists each step.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 63 gallons for this model. Its rated volume is 29 gallons. Compare the first hour rating with a household's busiest hour of hot-water use. If a home's peak hour needs more than 63 gallons, this rating does not cover it. If the peak hour needs less, it falls within the rating. The registry gives no figure for how the unit performs above that demand, so that remains unknown. To compare other sizes or fuels against the same test, use the selector by fuel, space and size.
This page does not give a running cost because it depends on your state's average residential gas price. The page calculates that cost from your ZIP, using the 185 therms figure at the medium draw pattern. The cost calculator for your own ZIP runs the same calculation for other models. No installed price range is published for the FMHR-30 4**. Its ratings fall outside the range the cost database's model was built on, and the range is not extended beyond it. To check models registered as a gas tank at the medium draw pattern, use the same-class replacement search by model number.
