The 622 kWh figure does not appear in the registry itself. This site calculated it from the model's UEF, the ratio of hot water delivered to energy used, which is 0.95 here. The calculation also uses the DOE test's daily hot-water draw for the very small draw pattern. That pattern stands for small units: a single bathroom, or a point-of-use heater under a sink. The underlying record comes from the DOE CCD, retrieved 2026-09-19. Your yearly use will differ from 622 kWh if your daily hot-water use differs from the test's draw. This page cannot tell how large that difference would be. The steps behind the figure are in how the annual cost is calculated.

The model's maximum flow rate in gallons per minute is 0.3. Together with the very small draw pattern, that rating is what the registry supports about fit: single-bathroom or point-of-use service. Households drawing hot water at several outlets at once fall outside that pattern, and the 622 kWh figure does not describe their use. The registry data gives no measurement for that larger demand, so this page does not say how the unit would perform there. Within its class, the model sits in the second-highest quarter for energy use, in line with its 152nd place noted above. To compare other models, use the selector by fuel, space and size or find a same-class replacement by model number.

This text does not state a running cost. The cost depends on your own utility's electricity tariff applied to the 622 kWh yearly use. The page works it out from your ZIP, so enter it in the cost calculator on your own ZIP. Because this model uses 7 kWh more than the class median, its cost at any given rate will be higher than a median unit's by the cost of that 7 kWh. Your tariff is unknown to this page, so no cost figure appears here. The installed price range is shown in its own block with its source and date. That range is a modeled installed-cost estimate, not a quote from an installer.
