The annual 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. That draw pattern covers small units, such as a single bathroom or a point-of-use heater under a sink. The figure describes the test conditions, not any particular household. Energy use under a different daily draw is not available on this page and is not estimated. The steps behind the calculation are set out in how the annual cost is calculated.

The class for this comparison is the 271 models registered as an electric tankless unit at the very small draw pattern. Its median is 615 kWh, and this model differs from it by 0 kWh. It ranks 77th lowest in energy use, which places it in the second-lowest quarter of its class. The comparison does not extend to gas units or to other draw patterns. The maximum flow rate in gallons per minute is 0.9. The 615 kWh figure fits the small applications described above. For a larger daily draw it does not apply, and no value is available here. To look for models in the same class, use find a same-class replacement by model number.

Running cost depends on your own electricity rate, so this text states no cost figure. The cost calculator on your own ZIP applies your utility tariff to the 615 kWh shown here. Because this model sits 0 kWh from the class median of 615 kWh, a model at the median would cost the same to run at the same rate. Any difference in cost between two models comes from their annual energy use and the rate applied to it. The modeled installed-cost range appears in its own block with its source and date and is not repeated here. If the draw pattern does not match your use, the selector by fuel, space and size covers other cases.
