Aquapower Mini-E 6-2
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 the Aquapower Mini-E 6-2, it uses 603 kWh of electricity a year. That figure is for the very small draw pattern, the standard daily hot-water usage DOE tests against. It is 12 kWh below the class median of 615 kWh, ranking 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 603 kWh figure was computed by this site, not taken from the registry. It starts from the registry's UEF, the ratio of hot water delivered to energy used. The registered UEF is 0.98. The site applies it to the daily hot-water draw that the DOE test uses for this draw pattern. The source is the DOE CCD, retrieved 2026-09-19. The figure holds only for electricity and the very small draw pattern. It is not a measurement of any one home. The registry also lists a maximum flow rate in gallons per minute of 0.6. That flow rate is a separate listed value and is not an input to the energy figure. See how the annual cost is calculated for the steps.
The class has 271 models, all registered as an electric tankless unit at the very small draw pattern. This unit uses 12 kWh less a year than the class median of 615 kWh. Its rank is 10th lowest energy use of 271, which puts it in the lowest quarter of its class. The very small draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. The figure suits a check on that kind of use. It does not describe a whole-house load, and this page has no energy figure for other draw patterns. To compare by fuel, space and size, use the water heater selector.
The running cost is not stated on this page. It depends on your own utility electricity rate, and this page does not know that rate. The cost calculator for your own ZIP applies your rate to the 603 kWh a year. The installed price range has its own block on the page, with its source and date. It is a modeled installed-cost range, not a quote, and is not restated here. If you need a same-class unit, find a replacement by model number using Mini-E 6-2. The 603 kWh figure stays the same whatever the rate; only the cost changes.
