The 206 therms figure does not come directly from the registry; this site computed it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw. That draw is the one set for the high draw pattern. For this model the UEF is 0.82, from the DOE CCD as retrieved on 2026-09-19. The result describes use under test conditions, not a meter reading from any home. A household that draws more or less hot water than the test assumes will use a different amount of gas. The full steps are set out in how this site calculates annual energy and cost.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. Among the 397 gas tankless models registered at that pattern, this one ranks 229th lowest in energy use. That puts it in the second-highest quarter of its class for energy use, in line with the gap to the median given above. The registry lists its maximum flow rate in gallons per minute as 4.3. Compare that figure with how many fixtures in the home run at the same time. For a smaller household that rarely overlaps hot-water use, this page has no energy figure, because the test pattern does not describe that use. To check other models in the same class, see the same-class replacement search by model number.

This page does not state a running cost in the text. The cost of 206 therms a year depends on your state's average residential natural gas price, so the page computes it from your ZIP. The same applies to the 24 therms gap to the class median: its yearly cost depends on that rate. You can enter a different ZIP in the cost calculator for your own ZIP. The installed price range appears in its own block, with its source and date. It is a modeled range, not a quote from an installer. Your actual gas bill is not available here, because it depends on your own hot-water use, not the test's.
