STATE GCR-40 2**

The 264 therms figure is computed by this site, not taken from the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. For the STATE GCR-40 2**, the UEF is 0.64, from DOE CCD data retrieved 2026-09-19. Among the 414 gas tank models registered at the high draw pattern, this unit ranks 236th lowest in energy use. That places it in the second-highest quarter of its class for energy use. The class median is 260 therms, so this model sits 4 therms above it. The steps behind the annual figure are set out in how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. For that use, the capacity figure to check is the first hour rating, the gallons of hot water available in the first hour from a full tank. This model lists a first hour rating of 80 gallons and a rated volume of 38 gallons. The 264 therms value holds only at the federal test's daily draw. A home that draws more or less hot water will not match it, and the registry gives no figure for other usage levels. To compare this unit with others in the same class, you can find a same-class replacement by model number. To look at units outside this class, use the selector by fuel, space and size.

Running cost is not stated in this text, because it depends on your state's average residential gas price. The page works it out from your ZIP in the cost calculator on your own ZIP. The 4 therms gap above the 260 therms median is an energy difference at the test draw, not a cost difference. What that gap costs you depends on your gas rate, and this text does not know that rate. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote. This registry data does not include figures for this model's service life, standby loss or energy use in a real household.
