E

Grade 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 unit's energy figure: the Aquapower DHC 3-2 uses 609 kWh of electricity a year at 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 it ranks 37th lowest of 271 comparable 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.

This model: 609 kWh

Solid line: this model (609 kWh). Dashed line: the class median.

What these figures mean

The figure of 609 kWh is not a registry entry. This site computed it from the registry's UEF and the daily hot-water draw that the DOE test assigns to the very small draw pattern. UEF, the ratio of hot water delivered to energy used, is 0.97 for this unit. The fuel is electricity, and the source is DOE CCD, retrieved 2026-09-19. The class median is 615 kWh across 271 electric tankless models at the same draw pattern, so this model sits 6 kWh below it. The method is described in how the annual cost is calculated. Real household use is not in this data, so the figure applies only at the test's daily draw.

At this draw pattern, the model is meant for small units: a single bathroom, or a point-of-use heater under a sink. Its maximum flow rate in gallons per minute is 0.3, as listed in the registry. That limit applies to anyone considering it for a larger load, because the figure of 609 kWh was computed only for the very small draw pattern and does not carry over to a bigger one. Its rank of 37th lowest of 271 places it in the lowest quarter of its class for energy use. The distance from the class median of 615 kWh is 6 kWh. To compare units by fuel, space and size, use the water heater selector.

The running cost is not stated here because it depends on your own utility electricity tariff. Multiplying 609 kWh a year, at the very small draw pattern, by your rate gives the yearly cost for this model. The cost calculator does this from your ZIP code. The modeled installed-cost range appears in its own block on this page with its source and date, so the text does not repeat it. A figure for any other draw pattern is not available for the Aquapower DHC 3-2. If you need a unit in the same class, you can find a same-class replacement by model number.
