EEMAX ECO 8

The figure of 615 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.96 with the daily hot-water draw that the DOE test assigns to the very small draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure applies only to that draw pattern, and this page has no value for any other. The unit ranks 77th lowest energy use of 271, which places it in the second-lowest quarter of its class. Its difference from the class median of 615 kWh is 0 kWh. Details of the calculation are in how the annual cost is calculated.

The registry lists a maximum flow rate in gallons per minute of 0.7 for this model. The very small draw pattern covers small units, meaning a single bathroom or a point-of-use heater under a sink, so that is the use the 615 kWh figure describes. The data suits a reader confirming a small, single-location application. It does not suit a reader who needs to supply several fixtures at once, because the data on this page does not show whether 0.7 gallons per minute meets that need. That reader can start from the selector by fuel, space and size or look for a same-class replacement by model number.

The running cost is not stated in the text, because it depends on your own utility electricity tariff. To estimate it, apply your rate per kilowatt-hour to 615 kWh. The cost calculator on your own ZIP does this for you. Because this model sits 0 kWh from the class median of 615 kWh, any cost gap against a median model in its class would come from the rate you pay, not from a registry difference. The figure reflects the federal test's daily draw. Your actual hot-water use in the home is not available here and may differ. The modeled installed-cost range appears in its own block on the page, with its source and date.
