STATE GPVNT-40 1**

This site calculates the 232 therms figure; the registry does not list it. The calculation combines the model'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. The registered UEF is 0.73, taken from the DOE Compliance Certification Database (CCD) and retrieved 2026-09-19. Among the 414 gas tank models registered at this draw pattern, the model ranks 33rd lowest for energy use. That places it in the lowest quarter of its class. The figure holds only at the test's daily draw. A household that uses more or less hot water will have a different total, and this page cannot state it. The steps are set out in how the annual figures are calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 91 gallons. Its rated volume is 38 gallons. The 232 therms figure assumes the daily draw of that pattern. The figure does not describe a smaller household, and this page does not have that household's annual use. A home that needs more than 91 gallons in its busiest hour needs more than the rating covers. To compare other models by fuel, space and size, use the water heater selector. To find a unit in the same class, use the same-class replacement lookup by model number.

This text does not state a running cost. The cost depends on your state's average residential gas price, so the page calculates it from your ZIP. The running cost calculator for your ZIP applies your rate to the 232 therms figure. The same condition applies to the 28 therms gap from the class median of 260 therms. What that gap is worth depends on your 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, and this text does not repeat its figures. The registry data has no service life or repair history, so this page cannot give them.
