The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.91. It also lists a maximum flow rate in gallons per minute of 0.5. The 649 kWh figure was computed by this site, not the registry, from that UEF and the DOE test's daily hot-water draw for the very small draw pattern. It is electricity use at that test draw only. Actual use with more or less hot water would differ, and the data here does not say by how much. The source is the DOE CCD, retrieved 2026-09-19.

Among the 271 models registered as an electric tankless unit at the very small draw pattern, this model sits 34 kWh above the class median of 615 kWh. Its rank is 265th lowest energy use of 271, which puts it in the highest quarter of its class for energy use. The unit suits small loads such as a bathroom or a point-of-use heater under a sink, the situations this draw pattern represents. It does not describe households with larger hot-water demand, because the 649 kWh figure is tied to the test draw. Anyone comparing sizes can use the water heater selector, or look up a same-class model with replacement by model number.

The running cost is not written here, because it depends on your own utility electricity tariff. To check it, apply your rate per kilowatt-hour to the 649 kWh figure, which is the value for the very small draw pattern. The cost calculator does this from your ZIP code. The steps behind the annual cost are in the methodology for water heaters. The modeled installed-cost range appears in its own block on the page with its source and date. It is a modeled range, not a quote, and it is not repeated here. If your hot-water use differs from the test draw, the cost of this model will differ as well, and that difference is not available in the data.
