EEMAX SPEX8208

The 615 kWh figure is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.96 for this model, and the DOE test's daily hot-water draw for the very small draw pattern. The source is DOE CCD, retrieved 2026-09-19. The fuel is electricity. The figure applies only at the very small draw pattern. The data gives no annual figure for this model at any other draw pattern, and this page does not estimate one. Energy use in a real home can differ from the federal test's daily draw, and the data does not say by how much.

Among the 271 models registered as an electric tankless unit at the very small draw pattern, this one 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. This draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. The maximum flow rate in gallons per minute is 0.8 for this model. The figure fits a low-demand use of that kind and does not describe a unit serving several fixtures at once. To look for another model in the same class, use the same-class replacement search by model number or the selector by fuel, space and size.

Running cost is not stated here because it depends on the reader's own utility electricity tariff. To turn 615 kWh into a cost, use the cost calculator on your own ZIP, which applies your local rate to that figure. The steps are described on the annual cost methodology page. A modeled installed-cost range for the EEMAX SPEX8208 appears in its own block on this page with its source and date. It is not a quote, and it is not repeated in this text. Without your rate, no running cost can be given for this model, and this page does not estimate one. The 615 kWh figure stays the same at any rate.
