The 260 therms figure is computed by this site, not taken from the registry. It combines two inputs. One is the registry's UEF, the ratio of hot water delivered to energy used, which is 0.65 for this model. The other is the DOE test's daily hot-water draw for the high draw pattern. The UEF comes from the DOE CCD, retrieved 2026-09-19. Against its class, the unit ranks 204th lowest in energy use of 414 gas tank models at that draw pattern. That places it in the second-lowest quarter of the class. Its gap to the class median of 260 therms is 0 therms, so its annual use is equal to the median. Every model in this comparison shares the same heater type and draw pattern.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The 260 therms figure applies to that level of daily use. The registry also lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 111 gallons. The rated volume is 48 gallons. For a household that matches the high draw pattern, the annual figure reflects the test's daily draw. For a household that uses less hot water per day, the data here gives no annual figure. That value is not available on this page. To compare tanks of other fuels or sizes, use the water heater selector by fuel, space and size.

The running cost is not stated in this text. It depends on the reader's state average residential gas price, so the page computes it from the reader's ZIP. The cost calculator on your own ZIP applies that rate to the 260 therms figure at the high draw pattern. The steps are set out in how the annual cost is calculated. This model's use equals the class median of 260 therms. At any given gas rate, its running cost therefore matches that of a median-use gas tank model in the class. The installed-cost range appears in its own block with its source and date. It is a modeled range, not a quote, and this text does not restate it.
