EEMAX SPEX75
0.96 UEF DOE CCD · 2026-09-19Grade E: where this UEF sits among the 271 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tankless unit, very small draw pattern (small units - a single bathroom, or a point-of-use heater under a sink).
If you are checking the EEMAX SPEX75, an electric tankless unit, this is its annual energy use. It uses 615 kWh of electricity a year at the very small draw pattern, the standard daily hot-water usage DOE tests against. That equals its class median of 615 kWh, a difference of 0 kWh.
Energy use per year
615 kWh a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.
That is equal to the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 77 of 271, lowest energy first.
Solid line: this model (615 kWh). Dashed line: the class median.

The 615 kWh figure was 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 DOE test's daily hot-water draw for the very small draw pattern. The fuel is electricity, and the source is DOE CCD, retrieved 2026-09-19. The figure describes the federal test's draw only. Actual household use depends on how much hot water is drawn, and this page has no measured household figure. The steps behind the calculation are set out in how the annual cost is calculated.
This model is registered at the very small draw pattern, meaning small units - a single bathroom, or a point-of-use heater under a sink. Its maximum flow rate in gallons per minute is 0.8. A household that draws hot water at several fixtures at once is outside what this draw pattern describes, and this page gives no figure for other draw patterns. Among the 271 models in its class, this one ranks 77th lowest for energy use, which places it in the second-lowest quarter. To compare within the same class, find a same-class replacement by model number or use the selector by fuel, space and size.
The running cost is not stated here because it depends on your own utility electricity tariff. To get the yearly running cost at the test's draw, apply your rate per kilowatt-hour to 615 kWh. The cost calculator on your own ZIP does this with the tariff for your location. If your real hot-water use is above or below the test's draw, the yearly energy will differ from 615 kWh, and the registry data does not say by how much. The modeled installed-cost range appears in its own block with its source and date. It is a modeled range, not a quote, and it is not repeated in this text.
