EEMAX SPEX4208T
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).
Checking this unit's figures? Under the very small draw pattern, the standard daily hot-water usage DOE tests against, the EEMAX SPEX4208T uses 603 kWh of electricity a year. That is 12 kWh below the class median of 615 kWh. It ranks 10th lowest of 271 models.
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 figure of 603 kWh comes from this site, not from the registry. It starts from the registry's UEF, the ratio of hot water delivered to energy used. That is combined with the DOE test's daily hot-water draw for this draw pattern. This model's UEF is 0.98. The source is the DOE CCD, retrieved 2026-09-19. The class is the 271 models registered as an electric tankless unit at the very small draw pattern. Against that class, the median is 615 kWh, and this unit sits 12 kWh below it. The method is set out in how the annual cost is calculated.
The registry lists this unit's maximum flow rate in gallons per minute as 0.4. The very small draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. The 603 kWh figure is meant for that use. Its 10th lowest energy use among 271 models places it in the lowest quarter of its class. A household that runs several fixtures at once is outside what this figure describes. The figure applies only to the very small draw pattern, and no value for larger draws is available on this page. To compare other fuels, spaces or sizes, use the selector by fuel, space and size.
The running cost depends on your own electricity tariff, so no cost is written in this text. To check it by hand, multiply 603 kWh by your rate per kWh. The cost calculator on your own ZIP does this with your local tariff. The gap of 12 kWh against the 615 kWh median changes a bill in proportion to that same rate. Actual use in a home depends on how much hot water is drawn, so it can differ from the test's daily draw. The installed price range is shown in its own block, with its source and date, as a modeled range and not a quote. For a same-class alternative to SPEX4208T, find a replacement by model number.
