AMERICAN HPTA-50 2**
3.68 UEF DOE CCD · 2026-09-19Grade B: where this UEF sits among the 426 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
Checking this model's energy use: AMERICAN HPTA-50 2**, an electric tank, uses 883 kWh a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,648 kWh below the class median of 3,531 kWh among 426 electric tank models. It ranks 48th lowest for energy use.

883 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 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 48 of 426, lowest energy first.
Solid line: this model (883 kWh). Dashed line: the class median.

UEF 3.68 · Grade B Price it on your ZIP
The registry lists a UEF, the ratio of hot water delivered to energy used, of 3.68 for this model. This site computed 883 kWh a year from that UEF and the DOE test's daily hot-water draw for the medium draw pattern; the registry does not publish that figure itself. The source is DOE CCD, retrieved 2026-09-19. The result is 2,648 kWh below the class median of 3,531 kWh. Ranked by energy use, the model is 48th lowest of 426, which places it in the lowest quarter of its class. The comparison covers only models registered as an electric tank at the medium draw pattern, so it says nothing about other fuels or other draw patterns. How the annual cost is calculated is set out on the methodology page.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 65 gallons, and the rated volume is 46 gallons. The medium draw pattern describes a typical three- or four-person household on a busy morning, and the 883 kWh figure applies to that pattern only. It is relevant to readers checking a unit of this size against that household. It does not cover households with a different daily draw, and the data give no annual energy for other draw patterns. The figure is a test-based calculation, not a measurement in a home. Readers sorting by fuel, space or size can use the water heater selector by fuel, space and size.
Running cost is not stated here because it depends on your own utility electricity tariff. It is the 883 kWh figure multiplied by your rate, and that rate is not in the data. The cost calculator on your ZIP computes it. The installed price range appears in its own block with its source and date; it is a modeled installed-cost range, not a quote. The model uses 2,648 kWh less than the class median of 3,531 kWh. The same rate applies to a smaller quantity of energy, but the cost difference depends on that rate. To compare against other units in its class, find a same-class replacement by model number. The limit of this page is that 883 kWh is a calculation at the federal test's draw, not a reading from a home.
