AMERICAN HPTU-50N 1**
3.45 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).
If you are checking this unit against a spec sheet: AMERICAN HPTU-50N 1** uses 942 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,589 kWh below the class median of 3,531 kWh.
Energy use per year
942 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 93 of 426, lowest energy first.
Solid line: this model (942 kWh). Dashed line: the class median.

UEF 3.45 · Grade B Price it on your ZIP
The figure of 942 kWh was 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 daily hot-water draw of the federal test. The model's UEF is 3.45. The figure holds only for the medium draw pattern, meaning a typical three- or four-person household on a busy morning. Among the 426 electric tank models registered at that pattern, this one ranks 93rd lowest for energy use. That puts it in the lowest quarter of its class. The source is DOE CCD, retrieved 2026-09-19.
Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 66 gallons. The rated volume is 46 gallons. Those figures are the ones to compare with your own peak demand. The energy figure suits a household whose use resembles the medium draw pattern. It does not describe a household that draws more or less hot water each day. For those cases, the energy use of this model is not available here. Treat 942 kWh as a reference only. To check the size and fuel of a different unit, use the water heater selector by fuel, space and size. To find a same-class replacement, enter the model number in the same-class replacement finder.
Running cost depends on your own utility electricity tariff, so this text states no cost figure. The cost calculator on your own ZIP applies your rate to 942 kWh. The method is explained under how the annual cost is calculated. The gap of 2,589 kWh from the class median of 3,531 kWh is a difference in kilowatt-hours. Its value in cost terms follows your rate. The installed price range appears in its own block with its source and date. It is a modeled installed-cost range, not a quote, so its figures are not repeated here. This page makes no claim about other draw patterns. The comparison of 426 models covers only electric tanks at the medium draw pattern.
