The 206 therms figure was calculated by this site. It is not taken from the registry. It 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. For this model the UEF is 0.82. The result describes test conditions. A household that draws more hot water than the federal test would use more gas, and one that draws less would use less. The source is DOE CCD, retrieved 2026-09-19. Among the 397 gas tankless models registered at the high draw pattern, this one ranks 229th lowest in energy use. That places it in the second-highest quarter of its class for energy use.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The 206 therms figure applies to that kind of use. It should not be quoted for a smaller household. A figure for a lighter draw pattern is not available in this data. The registry lists a maximum flow rate in gallons per minute of 4.8 for this unit. The data does not say whether that flow covers a given home's outlets running at the same time. The models ranked ahead of its 229th position use less gas at the same test draw. To compare them, you can find a same-class replacement by model number or use the selector by fuel, space and size.

The running cost is not stated in this text. The cost of 206 therms of natural gas a year depends on your state's average residential gas price. The page calculates it from your ZIP in the cost calculator on your own ZIP. The method is explained in how the annual cost is calculated. This model uses 24 therms more gas a year than the class median at the test draw. At any gas rate, it will therefore cost more to run than a median model at that same rate. The difference is the price of that extra gas. The installed price range is shown in its own block, with its source and date. It is a modeled range, not a quote.
