Aquapower Mini 2-1
0.99 UEF DOE CCD · 2026-09-19Grade C: 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 listing: the Aquapower Mini 2-1, an electric tankless unit, uses 597 kWh of electricity a year at the very small draw pattern, the standard daily hot-water usage DOE tests against. That is 18 kWh below the class median of 615 kWh among 271 models.
Energy use per year
597 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 3 of 271, lowest energy first.
Solid line: this model (597 kWh). Dashed line: the class median.

The figure of 597 kWh is not read directly from the registry. This site computed it from the registry's UEF and the DOE test's daily hot-water draw for this draw pattern. UEF, the ratio of hot water delivered to energy used, is 0.99 for the Mini 2-1 in the registry. The fuel is electricity, and the figure applies only at the very small draw pattern. The source is the DOE CCD, retrieved 2026-09-19. A household that draws more or less hot water than the federal test will use a different amount, and this page has no data for that case. The steps of the calculation are set out in how the annual cost is calculated.
Among the 271 models registered as an electric tankless unit at the very small draw pattern, this one ranks 3rd lowest for energy use. That places it in the lowest quarter of its class. Its 597 kWh is 18 kWh below the class median of 615 kWh. The registry lists a maximum flow rate in gallons per minute of 0.2. The pattern covers small units, meaning a single bathroom or a point-of-use heater under a sink. Loads beyond that fall outside the draw pattern this figure describes, and the registry data gives no energy value for them. To compare other fuels, spaces and sizes, use the water heater selector.
Running cost depends on your own electricity rate, so this text states no cost amount. The calculation is 597 kWh multiplied by the rate you pay per kilowatt-hour, at the very small draw pattern. The cost calculator on your own ZIP does this for you. The modeled installed-cost range appears in its own block on this page, with its source and date, and it is not a quote. To check this listing against another unit with the same fuel and draw pattern, find a same-class replacement by model number. The registry gives no measured household usage for the Aquapower Mini 2-1, so that value is not available.
