Aquapower DHC 5-2
0.97 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 verifying the Aquapower DHC 5-2, it uses 609 kWh of electricity a year for the very small draw pattern, the standard daily hot-water usage DOE tests against. That is 6 kWh below the class median of 615 kWh, and 37th lowest of 271 electric tankless models.
Energy use per year
609 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 37 of 271, lowest energy first.
Solid line: this model (609 kWh). Dashed line: the class median.

The 609 kWh figure is not a registry value. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for this draw pattern. The registry lists a UEF of 0.97 for the Aquapower DHC 5-2. The fuel is electricity, and the figure holds only for the very small draw pattern at the federal test's daily draw. Actual use in a home can differ if the household draws more or less hot water than the test assumes. The source is DOE CCD, retrieved 2026-09-19.
Against its class, the Aquapower DHC 5-2 sits 6 kWh below the median of 615 kWh, at 37th lowest of 271 models. That places it in the lowest quarter of its class for energy use. Both the rank and the gap are measured at the same very small draw pattern. That pattern covers small units, such as a single bathroom or a point-of-use heater under a sink. The registry lists a maximum flow rate in gallons per minute of 0.5 for this model. The figures here do not describe larger draws, and energy use for other draw patterns is not available on this page. For a different fuel, space or size, use the water heater selector, or find a same-class replacement by model number.
This page states no running cost in the text. Cost depends on the electricity tariff the reader pays, and that tariff is not in the data, so any figure written here would be an estimate. To apply the 609 kWh to your own rate, use the cost calculator on your ZIP. The method behind the annual cost is documented separately. Because this unit is 6 kWh below the class median of 615 kWh at the same draw pattern, its yearly cost difference from a median unit is that energy gap multiplied by your rate. This page does not compute that difference. The modeled installed-cost range appears in its own block with its source and date, and it is not a quote.
