The 615 kWh figure is calculated by this site rather than published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.96 with the test's daily hot-water draw. That draw belongs to the very small draw pattern. The fuel is electricity, and the source is DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw. A household that draws more or less hot water will use a different amount, and the data does not say by how much. The steps of the calculation are described under how the annual cost is calculated.

This model ranks 77th lowest in energy use of 271, which places it in the second-lowest quarter of its class. Its use is equal to the class median of 615 kWh, a difference of 0 kWh. The comparison covers only models registered as an electric tankless unit at the very small draw pattern, meaning small units such as a single bathroom or a point-of-use heater under a sink. The registry lists the maximum flow rate in gallons per minute as 0.2. The figure is relevant to those small uses. It does not describe a household with several fixtures running at once, which the data does not cover.

Running cost is not stated here because it depends on your own utility electricity tariff. Multiplying 615 kWh by your rate gives the yearly cost at the test draw, and the cost calculator that works from your own ZIP does this for you. Because this model sits at the class median of 615 kWh, its energy use at the test draw is the same as that of the middle model in the class. The modeled installed-cost range appears in its own block on this page with its source and date. To compare against another unit of the same class, you can find a same-class replacement by model number. The registry does not record how much hot water your household actually draws, so actual use is unknown.
