The figure of 135 therms is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, listed as 0.82 for this model, with the DOE test's daily hot-water draw for the medium pattern. That pattern stands for a typical household on a busy morning. The registry data was retrieved from the DOE CCD on 2026-09-19. The figure holds only at the federal test's draw. A household that uses more or less hot water than the test assumes will burn a different amount of gas. The maximum flow rate in gallons per minute is 3.6, and it is a separate rating that does not enter the annual figure.

The comparison covers the 80 models registered as a gas tankless unit at the medium draw pattern. Their median is 135 therms, and this model sits at 135 therms, a difference of 0 therms. It ranks 32nd lowest in energy use, which places it in the second-lowest quarter of its class. The figure applies most directly to a household whose use resembles the medium pattern. It applies less directly to a household whose daily use is far from the test's draw, and the registry gives no figure for that case. To compare against other units by fuel, space and size, use the water heater selector. To look for a unit in the same class, use the same-class replacement search by model number.

The running cost is not written here because it depends on your state's average residential gas price, and that price is not part of the registry data. The cost calculator on your own ZIP applies that price to the 135 therms shown for this model. The steps behind that calculation are set out in how the annual cost is calculated. The modeled installed-cost range has its own block on this page, with its source and date, and it is a modeled range, not a quote. Actual gas use in a specific home is not available from the registry, so it is not estimated here.
