EEMAX ECO POU 6
0.94 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 checking the EEMAX ECO POU 6: it uses 628 kWh of electricity a year at the very small draw pattern, the standard daily hot-water usage DOE tests against. That is 13 kWh above the 615 kWh class median. It ranks 188th lowest in energy use of 271 models.
Energy use per year
628 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 188 of 271, lowest energy first.
Solid line: this model (628 kWh). Dashed line: the class median.

The annual figure for the EEMAX ECO POU 6 is 628 kWh of electricity. This site computed it, not the registry, from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.94 for this model. The calculation also uses the DOE test's daily hot-water draw for the very small draw pattern. The source is DOE CCD, retrieved 2026-09-19. The comparison group is the 271 electric tankless models registered at this draw pattern. Their median is 615 kWh, and this unit sits 13 kWh above it. Its rank is 188th lowest energy use, which places it in the second-highest quarter of its class.
The figure applies only at the test's very small draw pattern, meaning small units such as a single bathroom or a point-of-use heater under a sink. The registry lists a maximum flow rate in gallons per minute of 0.5 for this model. A household that draws more hot water than that pattern, or needs a flow above 0.5, is outside what this figure describes, and this page has no annual energy figure for other draw patterns. The 13 kWh gap from the median is a difference at the test draw, not a measured difference in a home. To compare other units by fuel, space and size, use the water heater selector, or find a same-class replacement by model number.
The running cost is not written here because it depends on your own utility electricity rate. The annual energy is 628 kWh, so the cost follows from what you pay per kilowatt-hour. The cost calculator applies the rate for your ZIP. The class median of 615 kWh priced at the same rate shows how the 13 kWh gap becomes a cost gap on your tariff. The calculation method explains how the annual cost is worked out. A modeled installed-cost range appears in its own block on this page with its source and date. It is not a quote and is not restated here. Real use in a home can differ from 628 kWh. The registry does not report measured household use, so that difference is unknown.
