The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.96 for this unit. This site combined that UEF with the DOE test's daily hot-water draw for the very small draw pattern. The result is 615 kWh of electricity a year. The registry does not publish that annual figure itself, so it is a site calculation. It applies only to the test draw. A household that draws more or less hot water than the test will use a different amount. The data was retrieved from DOE CCD on 2026-09-19. The method is described in how the annual cost is calculated.

Among the 271 models registered as an electric tankless unit at the very small draw pattern, this model has the 77th lowest energy use. That places it in the second-lowest quarter of its class. Its 615 kWh equals the class median of 615 kWh, so the difference is 0 kWh. The unit has a maximum flow rate in gallons per minute of 0.3. The very small draw pattern covers small units, such as a single bathroom or a point-of-use heater under a sink. A larger household load falls outside the pattern this figure describes. The flow rate of 0.3 is the only capacity figure in this data, so nothing more is stated about larger demand.

The running cost depends on your own electricity rate, which is not in this data, so no cost is written here. Multiply 615 kWh by your rate per kilowatt-hour to get a yearly figure at the test draw. The cost calculator on your own ZIP does this with the utility tariff for your area. The installed price range is shown in its own block with its source and date. It is a modeled range, not a quote.

Compare only units at the very small draw pattern, or the energy figures will not match.
