The figure of 615 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, of 0.96 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 figure applies only at that test draw. A household that draws more or less hot water than the test assumes will use a different amount, and the registry does not give a measured value for any home. The calculation steps are set out in how the annual cost is calculated.

Among the 271 models registered as an electric tankless unit at the very small draw pattern, this one ranks 77th lowest energy use. That places it in the second-lowest quarter of its class. Its distance from the class median of 615 kWh is 0 kWh, so at the test draw it matches a typical model in that class. Its maximum flow rate in gallons per minute is 0.5. The draw pattern describes small units, such as a bathroom or a point-of-use heater under a sink, and this unit is compared only within that group. Households whose hot-water demand exceeds that draw pattern are outside what this figure describes. To look at other models in the same class, use find a same-class replacement by model number.

The running cost is not stated in the text, because it depends on your own utility electricity tariff. The annual energy of 615 kWh is the quantity your rate is applied to, and it holds only at the very small draw pattern. Enter your ZIP in the cost calculator on your own ZIP to see the result at your local rate. The modeled installed-cost range appears in its own block on this page with its source and date, and it is not repeated here. If you are comparing across fuel, space or size, the selector by fuel, space and size covers those options. The registry data used here does not include any cost figure for this model.
