Aquapower DHC-E 10
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 this unit's energy figure: the Aquapower DHC-E 10, an electric tankless unit, uses 628 kWh a year in the very small draw pattern, the standard daily hot-water usage DOE tests against. That is 13 kWh above the class median of 615 kWh, and it ranks 188th lowest 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 figure of 628 kWh is electricity use at the federal test's daily hot-water draw for the very small draw pattern. It is not a measurement taken in any home. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.94 for the Aquapower DHC-E 10, and from the DOE test's daily hot-water draw for that pattern. The source is DOE CCD, retrieved 2026-09-19. The unit's maximum flow rate in gallons per minute is 1. The method behind the annual figure is described on its own page. A household that draws more or less hot water than the test assumes will use a different amount.
Against its class, the DHC-E 10 sits 13 kWh above the median of 615 kWh, among 271 models registered as an electric tankless unit at the very small draw pattern. Its rank is 188th lowest energy use of 271, which places it in the second-highest quarter of the class for energy use. The spread of values across the class is not available on this page. This draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. A reader with a larger load or a different fuel can compare options with the water heater selector. The figure does not carry over to other draw patterns, and no value for them is available here.
The running cost is not stated in this text, because it depends on the electricity tariff the reader pays. Multiplying 628 kWh by your own rate per kWh gives the yearly cost at the test's draw, and the cost calculator does this from your ZIP. The 13 kWh gap to the class median converts to a cost the same way. Measured use in a home is not available, so the result holds only for the very small draw pattern. The modeled installed-cost range appears in its own block on the page with its source and date, and it is not a quote. To look for a unit of the same class as the Aquapower DHC-E 10, you can find a same-class replacement by model number.
