EEMAX SPEX95

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 the DOE CCD, retrieved 2026-09-19. Because the result depends on that standard draw, a household that uses more or less hot water than the test will see a different total. The method is set out on the methodology page for annual cost, including how the inputs are combined.

Among the 271 models registered as an electric tankless unit at the very small draw pattern, this unit ranks 77th lowest energy use, which puts it in the second-lowest quarter of its class. Its 615 kWh equals the class median of 615 kWh, a difference of 0 kWh. The comparison covers only models in that class and draw pattern. It does not compare against gas or storage heaters. The maximum flow rate in gallons per minute listed for this model is 0.9. The draw pattern describes small units, meaning a single bathroom or a point-of-use heater under a sink, so a household with several fixtures running at once is outside what this figure describes.

The running cost depends on your own utility electricity tariff, so this text gives no cost figure. To check it, multiply 615 kWh by your price per kilowatt-hour, or use the cost calculator for your own ZIP. The result holds only for the very small draw pattern at the federal test's daily draw. Energy use in a specific home at its actual draw is not available from the registry and is not estimated here. The installed-price range appears in its own block on the page as a modeled range, not a quote.
