The figure of 609 kWh 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, which is 0.97 for this model, with the DOE test's daily hot-water draw for the very small draw pattern. The source is DOE CCD, retrieved 2026-09-19. The class median is 615 kWh, so this model sits 6 kWh below it, measured at that one test condition only. Real use in a home depends on how much hot water is drawn, and the data does not show that. The method behind the figure is set out in how the annual cost is calculated.

The registry lists a maximum flow rate in gallons per minute of 0.3 for this model. The very small draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. Among the 271 models registered as an electric tankless unit at this pattern, 37th lowest energy use places it in the lowest quarter of its class. That suits a reader comparing units for single-point use. It does not suit a reader whose demand is several fixtures at once, because the flow rate of 0.3 and the figure of 609 kWh say nothing about other draw patterns. To compare against a unit of the same class, use the same-class replacement search by model number.

The running cost is not stated here because it depends on your own utility electricity tariff, which this page does not know. To estimate it, multiply 609 kWh by your price per kilowatt-hour, or enter your ZIP in the cost calculator for your own ZIP. The same multiplication applied to 6 kWh gives the yearly cost gap from the class median of 615 kWh. The modeled installed-cost range appears in its own block with its source and date; it is a modeled range, not a quote, and is not repeated in this text. If fuel, space or size do not fit your case, the selector by fuel, space and size covers other options. Energy figures rest on data retrieved 2026-09-19 and may change if the registry changes.
