STATE G6-US4040NV 5**

This site calculates the 264 therms figure; the registry does not publish it. The calculation 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. This model's UEF is 0.64. The high draw pattern stands for a larger household, or one where showers and laundry overlap. If your household uses more or less hot water than the test assumes, your gas use will differ from 264 therms. The registry values come from the DOE CCD, retrieved 2026-09-19. The steps behind the figure are explained on the page about how the annual cost is calculated.

This model is compared with the 414 models registered as a gas tank at the high draw pattern. It ranks 236th lowest in energy use among them. That puts it in the second-highest quarter of its class for energy use. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 83 gallons. Its rated volume is 38 gallons. These figures match a reader checking a gas tank for a household close to the high draw pattern. If your goal is lower annual gas use within this class, the models ranked ahead of it use less gas at the same draw pattern. To see those models, look up this one on find a same-class replacement by model number.

The text does not give a running cost. The cost of 264 therms a year depends on your state's average residential gas price, so the page calculates it from your ZIP. The 4 therms gap to the class median is also measured in gas, not money. What that gap costs depends on the same local rate. The page does not estimate either amount. Both values also assume the test's daily hot-water draw. A household that uses less hot water would use less gas in a year, but this page does not have data on how much less. The installed price range appears in its own block, with its source and date. It is a modeled range, not a quote. To see the cost at your own rate, use the cost calculator on your own ZIP.
