The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.92 for this model. This site computed 120 therms a year from that UEF and the DOE test's daily hot-water draw for the medium draw pattern. The registry does not publish the annual figure itself. The medium pattern represents a typical household on a busy morning. The figure is for natural gas only and comes from DOE CCD, retrieved 2026-09-19. A household that uses more or less hot water than the test assumes will see a different annual figure.

Compare it with the 80 models registered as a gas tankless unit at the medium draw pattern. This model sits 15 therms below their median of 135 therms. Its rank of 3rd lowest puts it in the lowest quarter of its class for energy use. This suits a reader confirming how a listed unit's energy use compares with its class. The registry lists a maximum flow rate in gallons per minute of 4.1. That rating describes flow capacity, not annual energy, so it does not affect the rank. Flow at other inlet conditions is not available in this data.

This figure suits a reader checking a listing at the medium draw pattern. It does not suit a comparison at another draw pattern, because the 135 therms median applies only to the medium one. The running cost is not stated in the text. It depends on your state's average residential gas price, applied to 120 therms a year. The cost calculator does that on your own ZIP, and the annual cost methodology explains the steps. To compare against another unit of the same class, use the same-class replacement search by model number. The installed-price range appears in its own block, with source and date, as a modeled range and not a quote.
