EEMAX SPEX80T
0.98 UEF DOE CCD · 2026-09-19Grade D: 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 this figure, the EEMAX SPEX80T uses 603 kWh of electricity a year at the very small draw pattern, the standard daily hot-water usage DOE tests against. That is 12 kWh below the class median of 615 kWh across 271 electric tankless models, ranking 10th lowest.
Energy use per year
603 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 below the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 10 of 271, lowest energy first.
Solid line: this model (603 kWh). Dashed line: the class median.

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.98 for this model. This site multiplies that efficiency into the DOE test's daily hot-water draw for the very small draw pattern to reach 603 kWh. The registry does not publish that annual figure itself. The source is DOE CCD, retrieved 2026-09-19. The figure holds only for that test draw, so a household that draws more or less hot water will use a different amount. The method is written out in how the annual cost is calculated.
Against its class, the unit sits 12 kWh below the median of 615 kWh, at 10th lowest energy use of 271. That places it in the lowest quarter of the class for energy use. The very small draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. The registry gives a maximum flow rate in gallons per minute of 0.8. The comparison says nothing about larger draw patterns, and it does not cover gas or heat pump models. Outlet temperature rise and inlet water temperature are not available in this data. If you need a same-class alternative, find a same-class replacement by model number.
The running cost is not stated here because it depends on your own electricity tariff. The 12 kWh gap from the class median is an energy difference at the test draw, and its cost changes with your rate. The same 603 kWh costs more or less depending on where the unit is installed. To see a cost for your address, use the cost calculator on your own ZIP. The modeled installed-cost range appears in its own block on this page, with its source and date. It is a modeled range, not a quote.
