The figure of 622 kWh is calculated by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.95 with the DOE test's daily hot-water draw for the very small draw pattern. The source is the DOE CCD, retrieved 2026-09-19. The figure holds only under that test draw. A household that draws more or less hot water than the test assumes will use a different amount. The registry also lists a maximum flow rate in gallons per minute of 1.1. That value describes flow capacity and is not part of the energy calculation.

This unit is compared with the 271 models registered as an electric tankless unit at the very small draw pattern. It sits 7 kWh above the class median of 615 kWh, and its rank of 152nd lowest energy use places it in the second-highest quarter of its class. The registry data does not show whether that difference matters in a given home. The comparison suits small units: a single bathroom, or a point-of-use heater under a sink. It does not describe a home with a larger daily draw, and that reader can use the water heater selector to filter by fuel, space and size, or find a same-class replacement by model number.

The running cost is not written here because it depends on your own utility electricity tariff. Multiplying 622 kWh by your rate per kilowatt-hour gives the yearly cost at the test draw. The cost calculator does this from your ZIP, and how the annual cost is calculated explains the method. The same rate applied to the class median of 615 kWh would differ from this model's cost only by the 7 kWh gap. Your actual hot-water use is not measured here, so the result is an estimate at the federal test draw, not a prediction for your household. The installed price range is shown in its own block, with its source and date.
