This site calculated the 238 therms figure. The registry does not publish it. The calculation combines the registry's UEF with the DOE test's daily hot-water draw for the high draw pattern. The UEF, the ratio of hot water delivered to energy used, is 0.71 for this model. The source is the DOE CCD, retrieved 2026-09-19. This site compared the model with the 414 models registered as a gas tank at the high draw pattern. It ranks 84th lowest for energy use of 414, which puts it in the lowest quarter of its class. The figure holds only at the test's daily draw. The data does not show how much gas the unit uses in a home that draws more or less hot water. The method behind the annual energy and cost figures explains each step.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The 238 therms figure describes that kind of use and no other. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 93 gallons. The rated volume is 28 gallons. The first hour rating does not cover a peak hour that needs more than 93 gallons. A household with lower use falls under a different draw pattern, so this energy figure does not describe it. To compare other units by fuel, space and size, use the water heater selector by fuel, space and size. To match a unit that is already installed, find a same-class replacement by model number.

The running cost does not appear in this text because it depends on your state's average residential gas price. The page applies that rate to the 238 therms figure at the high draw pattern, using your ZIP code. The cost calculator for your own ZIP shows the result. At any single gas rate and the same test draw, the 22 therms gap noted above keeps this model's cost below that of a unit at the class median. An installed price range is not available for this model. Its ratings lie outside the range that the cost database's model was fitted on. The page does not extend that range to cover them.
