STATE GCGH-50 2**

The 269 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 draw for this pattern. For this model the UEF is 0.63, from DOE CCD data retrieved 2026-09-19. The result holds only at that test draw. A home that uses more or less hot water than the test assumes will burn a different amount of gas. That amount is not available here, because the registry does not record household use. The method behind the annual energy and cost figures explains each input and how they combine.

The high draw pattern describes a larger household, or one where showers and laundry overlap. This unit's first hour rating, the gallons of hot water available in the first hour from a full tank, is 76 gallons. Its rated volume is 48 gallons. Among the 414 models registered as a gas tank at the high draw pattern, it is 320th for lowest energy use. That places it in the highest quarter of its class for energy use. For a household whose use is closer to a lower draw pattern, the high-pattern figure does not apply, and this page has no figure for that case. To check other units in the same class, use the same-class replacement search by model number.

The running cost is not written in this text. It depends on your state's average residential gas price, so the page computes it from your ZIP. The same 269 therms gives a different cost in each state, so no single cost figure is valid everywhere. The 9 therms gap above the class median is priced at the same rate as the rest of the gas use. The cost calculator for your own ZIP applies that rate to this model. The installed price range sits in its own block on this page, with its source and date. It is a modeled range, not a quote, and this text does not restate its figures.
