This site computes the 206 therms figure; the registry does not publish it. The calculation 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, from DOE CCD data retrieved 2026-09-19. The result holds only at that test draw. A home that uses more or less hot water will use a different amount of gas. The steps are set out in how this site calculates annual energy and cost. If your own check gives a figure other than 206 therms, first compare the draw pattern and the UEF you used. Both change the result.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. The registry lists this unit's maximum flow rate in gallons per minute as 4.3. Among the 397 gas tankless units registered at the high draw pattern, this model sits in the second-highest quarter of its class for energy use. It is 24 therms above the 182 therms median. The 206 therms figure describes a household whose use matches the high pattern. It does not describe a smaller household, and this page has no energy figure for one. To compare models in the same class by model number, use the same-class replacement finder.

The text of this page states no running cost. The cost of 206 therms of natural gas a year depends on your state's average residential gas price. For that reason, the page computes it from your ZIP instead of giving one figure. This model uses 24 therms more than the 182 therms class median at the high draw pattern. At the same gas price, its cost is therefore above that of a model at the median. How far above depends on your rate. Enter your ZIP in the running-cost calculator for your own ZIP to see it. The installed price range in its own block is a modeled range, not a quote. It is separate from the running cost.
