The 615 kWh figure 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. Because the figure rests on that standard draw, it describes the test conditions and not any particular household's use. Among the 271 models registered as an electric tankless unit at this draw pattern, this one ranks 77th lowest for energy use, in the second-lowest quarter of its class. Its difference from the class median of 615 kWh is 0 kWh.

The very small draw pattern covers small units, such as a single bathroom or a point-of-use heater under a sink. The registry lists a maximum flow rate in gallons per minute of 0.6 for this model, so it suits a load at or below that flow. It does not suit a load that needs more than 0.6 gallons per minute, because the listed maximum would be exceeded. For a different fuel, space or size, the water heater selector filters by those inputs. To look for a unit in the same class, use the replacement finder by model number. Rank and median comparisons on this page hold only within the class of 271 models.

The running cost is not stated in the text, because it depends on your own utility electricity tariff. Applying your rate to 615 kWh in the cost calculator for your own ZIP gives the yearly electricity cost at the test's draw. The method behind the annual cost is documented separately. A household that draws more or less hot water than the very small draw pattern will use a different amount than 615 kWh, and the registry data does not say by how much. The installed price appears in its own block with its source and date, as a modeled range and not a quote. Because this model's energy use equals the class median of 615 kWh, it sits neither above nor below a median model in the class.
