Aquapower DHC-E 12
0.93 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).
The Aquapower DHC-E 12 uses 635 kWh of electricity a year at the very small draw pattern, the standard daily hot-water usage DOE tests against. That is 20 kWh above the class median of 615 kWh among 271 electric tankless models, and 218th lowest in energy use.
Energy use per year
635 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 218 of 271, lowest energy first.
Solid line: this model (635 kWh). Dashed line: the class median.

The registry lists the Aquapower DHC-E 12, an electric tankless unit, with a UEF, the ratio of hot water delivered to energy used, of 0.93. This site computed 635 kWh a year from that UEF and the DOE test's daily hot-water draw for the very small draw pattern. The registry does not publish the annual figure itself. The source is DOE CCD, retrieved 2026-09-19. The figure describes the test's draw only. It does not describe how much hot water any particular household uses, and metered consumption for this model is not available. This page gives no figure for other draw patterns.
The very small draw pattern covers small units: a single bathroom, or a point-of-use heater under a sink. At that pattern this model sits 20 kWh above the class median of 615 kWh. That puts it in the highest quarter of its class for energy use, at 218th lowest of 271. Its maximum flow rate in gallons per minute is 1.2. The figure fits a reader comparing this model with others in the same class for a single bathroom or a sink. It does not apply to a reader with larger demand, because it was computed only for the very small draw pattern. The water heater selector filters by fuel, space and size, and you can find a same-class replacement by model number.
The running cost is not written here because it depends on your own utility electricity tariff. Multiplying 635 kWh by your rate gives the yearly cost at this draw pattern, and the cost calculator does this from your ZIP. The 20 kWh gap to the class median is also priced at your rate, so the cost of that gap follows your tariff as well. The page on how the annual cost is calculated sets out the method. The modeled installed-cost range appears in its own block on this page with its source and date, and it is not a quote. Actual use above or below the test's daily draw would change the annual energy.
