AMERICAN HPTA-40 2**
3.6 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).
You are checking one model's yearly energy use. AMERICAN HPTA-40 2** uses 902 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,629 kWh below the class median of 3,531 kWh. Its rank is 53rd lowest of 426.
Energy use per year
902 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 53 of 426, lowest energy first.
Solid line: this model (902 kWh). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's rated tank size lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

UEF 3.6 · Grade B Price it on your ZIP
The 902 kWh figure is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw. The registry lists this model's UEF as 3.6, and the draw pattern is medium. The fuel is electricity, and the source is DOE CCD, retrieved 2026-09-19. The figure holds only at the medium draw pattern. A household that draws more or less hot water would use a different amount, and the registry data gives no value for those cases. The steps are set out in how the annual cost is calculated.
Among 426 electric tank models registered at the medium draw pattern, the class median is 3,531 kWh a year. This model sits 2,629 kWh below that median. Its rank is 53rd lowest energy use of 426, which places it in the lowest quarter of its class. Its rated volume is 36 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 55 gallons. These figures suit a household whose hot-water use resembles the medium draw pattern, a typical household on a busy morning. They do not show whether the tank covers a household with heavier use. Compare size with your own demand in the water heater selector by fuel, space and size.
Running cost is not stated here because it depends on your own utility electricity tariff. Multiply 902 kWh by your rate per kilowatt-hour to see the yearly cost at the medium draw pattern. The cost calculator on your own ZIP does this with the tariff for your area. The same 902 kWh costs more at a higher rate and less at a lower one. An installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it. The 2,629 kWh gap to the 3,531 kWh median is an energy figure, not a cost. To compare with another unit, find a same-class replacement by model number.
