The figure of 184 therms is computed by this site, not published by the registry. The registry gives a UEF, the ratio of hot water delivered to energy used, of 0.92. This site combines that value with the DOE test's daily hot-water draw for the high draw pattern. The steps are described in how the annual cost is calculated. The source is DOE CCD, retrieved 2026-09-19. The registry also lists a maximum flow rate in gallons per minute of 4.1. That flow rate is a rated limit and is separate from the annual energy figure. The annual figure applies only to the test's daily draw.

Against its class, this unit sits 2 therms above the median of 182 therms. It ranks 207th lowest in energy use among 397 models. That places it in the second-highest quarter of its class for energy use. The class is gas tankless units registered at the high draw pattern. The data suits a check for a larger household, or one where showers and laundry overlap. For that use, the figure of 184 therms is the number to compare. It does not describe a household with a smaller daily draw, and this page has no figure for other draw patterns. The data does not show whether a gap of 2 therms changes anything in use. A same-class replacement by model number can be looked up for comparison.

The running cost is not stated in this text. It depends on your state's average residential gas price. The cost calculator on your own ZIP applies that price to 184 therms. The result holds only for the high draw pattern and the federal test's daily draw. A household with different hot-water use will have a different gas figure. The registry does not report measured use in homes, so this page cannot state it. 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 restate it. The class median of 182 therms carries the same condition, because it also uses the test's draw.
