The 249 therms figure is calculated by this site. The registry does not list it. It combines the registered UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw that the DOE test uses for the high draw pattern. This model's UEF is 0.68. The source is the DOE CCD, retrieved 2026-09-19. Among the 414 gas tank models at the high draw pattern, this one ranks 164th lowest in energy use. That puts it in the second-lowest quarter of its class for energy use. The calculation steps are set out on the page explaining how the annual cost is 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 82 gallons. Its rated volume is 46 gallons. Both values describe capacity under the federal test's conditions, not in any particular home. The 249 therms figure assumes the high draw pattern's daily use. For a household that uses less hot water, this data gives no annual energy figure. To compare other units, use the water heater selector by fuel, space and size. To match an existing unit, find a same-class replacement by model number.

The running cost is not written in this text. The cost of 249 therms of natural gas depends on your state's average residential gas price, so the page calculates it from your ZIP code. Enter your ZIP in the cost calculator for your own ZIP to see the figure at your rate. At any single gas price, this model's cost stays below the cost of a class-median model, because it uses 11 therms less gas than the 260 therms median. The size of that cost gap depends on your rate, so it is not given here. The installed price range has its own block on this page, with its source and date. That range is a modeled installed cost, not a quote.
