EEMAX SPEX2412
0.95 UEF DOE CCD · 2026-09-19Grade F: 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 verifying the EEMAX SPEX2412, this site calculates 622 kWh of electricity a year for it at the very small draw pattern, the standard daily hot-water usage DOE tests against. That is 7 kWh above the class median of 615 kWh, and the unit ranks 152nd lowest of 271 for energy use.
Energy use per year
622 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 above the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 152 of 271, lowest energy first.
Solid line: this model (622 kWh). Dashed line: the class median.

The figure is computed by this site, not listed by the registry. It uses the registry's UEF, the ratio of hot water delivered to energy used, together with the DOE test's daily hot-water draw for the very small draw pattern. The EEMAX SPEX2412 has a UEF of 0.95, which gives 622 kWh of electricity a year. The class is the 271 models registered as an electric tankless unit at that draw pattern, and its median is 615 kWh. This unit sits 7 kWh above that median. Its rank is 152nd lowest of 271, which puts it in the second-highest quarter of its class for energy use. The source is DOE CCD, retrieved 2026-09-19.
The figure applies to small units, meaning a single bathroom or a point-of-use heater under a sink. The EEMAX SPEX2412 lists a maximum flow rate in gallons per minute of 0.2. For a load of that kind, 622 kWh is the number to set against the 615 kWh class median. It does not describe a larger draw pattern, and the data available here give no energy figure for one. A household with more fixtures than that would need figures for a larger draw pattern, which this page does not provide. The water heater selector by fuel, space and size filters on those inputs, and you can find a same-class replacement by model number.
Annual energy is not a running cost. The cost is the 622 kWh multiplied by your own electricity rate, and that rate depends on your utility tariff, so this text states no cost. The cost calculator applies your ZIP to the figure, and the method for the annual cost is documented separately. At the very small draw pattern and the same rate, this unit uses 7 kWh a year more than the 615 kWh median, so the gap in cost is that difference times your rate. A modeled installed-cost range is shown in its own block with its source and date. It is not a quote.
