STATE GCR-30 2**
0.63 UEF DOE CCD · 2026-09-19Grade E: 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 GCR-30 2**, this gas tank water heater uses 176 therms of natural gas a year. That figure is for the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 9 therms below the 185 therms median of the 288 gas tank models at that pattern.
Energy use per year
176 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 62 of 288, lowest energy first.
Solid line: this model (176 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.

This site calculates the 176 therms figure; the registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw that the DOE test sets for the medium pattern. This model's UEF is 0.63, taken from the DOE CCD record retrieved 2026-09-19. The result holds only at that test draw. A household drawing more or less hot water will use a different amount, and that amount is not available in this data. Within its class, the model ranks 62nd lowest in energy use of 288 models. The steps behind the figure are set out in how the annual cost is calculated.
The medium pattern describes a typical household's daily hot-water use, and the 176 therms figure assumes that use. The tank's rated volume is 29 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 63 gallons. A plumber or seller checking a quote can compare that rating with the household's busiest hour. A home whose peak hour needs more than 63 gallons falls outside what this rating covers. This data has no energy figure for this model at other draw patterns. To check other gas tanks tested at the medium pattern, use a same-class replacement search by model number.
This page does not state the running cost because it depends on your state's average residential natural gas price. The page calculates it from your ZIP and the 176 therms test-draw figure. Enter your ZIP in the cost calculator on your own ZIP to see it. Two households with this model and the same draw will pay different amounts if their gas prices differ. No installed price range is published for the STATE GCR-30 2**. Its ratings, including the 0.63 UEF and the 29-gallon volume, lie outside the range the cost database's model was fitted on. The site does not apply that model outside its fitted range, so no installed price is shown.
