Aquapower DHC 6-2
0.96 UEF DOE CCD · 2026-09-19Grade E: 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 model's energy figure: the Aquapower DHC 6-2, an electric tankless unit, uses 615 kWh of electricity a year at the federal test's very small daily hot-water draw. That is 0 kWh from the class median of 615 kWh across 271 models.
Energy use per year
615 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 equal to the median of 615 kWh for the 271 models registered in the same heater type and draw pattern; it ranks 77 of 271, lowest energy first.
Solid line: this model (615 kWh). Dashed line: the class median.

The figure of 615 kWh is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.96 for this model, and from the daily hot-water draw that DOE assigns to this draw pattern. A draw pattern, the standard daily hot-water usage DOE tests against, is described here as small units: a single bathroom, or a point-of-use heater under a sink. The source is DOE CCD, retrieved 2026-09-19. The figure applies only at that test draw. Actual household use can differ, and this page has no measured value for it.
The comparison group is the 271 models registered as an electric tankless unit at the very small draw pattern. This model ranks 77th lowest energy use of 271, in the second-lowest quarter of its class. Its difference from the class median of 615 kWh is 0 kWh, so it equals the median rather than falling above or below it. The maximum flow rate in gallons per minute is 0.6. These figures relate to the small loads named above; a larger draw pattern is outside what this figure covers. The water heater selector filters by fuel, space and size, and the same-class replacement search by model number lists units in this class.
The running cost is not written here because it depends on your own utility electricity tariff. Multiply the 615 kWh by your rate per kWh, or enter your ZIP in the cost calculator, which does this for you. The steps are set out in how the annual cost is calculated. A higher or lower rate changes the cost in proportion, while the 615 kWh stays the same, and the result holds only at the very small draw pattern. The installed price range appears in its own block on this page, with its source and date, as a modeled range and not a quote. Its figures are not repeated here.
