STATE 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).
If you are verifying the STATE GCR-30R 4**, this gas tank uses 185 therms of natural gas a year at the federal test's daily hot-water draw. That figure is for the medium draw pattern, the standard daily hot-water usage DOE tests against. It is 0 therms from its class median of 185 therms, ranking 89th lowest of 288.
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
The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.6 for the STATE GCR-30R 4**. The 185 therms figure was calculated by this site, not taken from the registry. It combines that UEF with the DOE test's daily hot-water draw for the medium pattern. The registry record comes from DOE CCD, retrieved 2026-09-19. So the figure describes use under the federal test, not a metered reading from any home. It does not cover a household that uses more or less hot water each day than the test assumes. The registry does not give that household's actual gas use. The inputs and steps are set out in how the annual energy and cost figures are calculated.
Its 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. If you are matching this unit to a home's busiest hour, compare that hour's demand with the 62 gallons. A home that needs more than 62 gallons in its peak hour is outside what this rating covers. Its energy use against the class median is given above. Ranking 89th of 288 gas tank models puts it in the second-lowest quarter of its class for energy use. Models ranked ahead of it use no more gas under the same test. To see listed alternatives in the same class, find a same-class replacement by model number.
The running cost is not given in this text because it depends on your state's average residential gas price. The page works it out from your ZIP by applying that price to the 185 therms of natural gas. So the same 185 therms can cost different amounts each year in different states. To calculate it with your own rate, use the water heater cost calculator for your ZIP. An installed price range is not available for the STATE GCR-30R 4**. Its ratings are outside the range the cost database's model was fitted on. This page does not extend the model past that range, so it shows no installed price. Other units are listed by fuel, space and size in the water heater selector.
