AMERICAN STANDARD WATER HEATERS ENS50T-DR***
0.92 UEF DOE CCD · 2026-09-19Grade G: 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 the AMERICAN STANDARD WATER HEATERS ENS50T-DR***, it uses 3,531 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That equals its class median of 3,531 kWh, a difference of 0 kWh.
Energy use per year
3,531 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 equal to the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 213 of 426, lowest energy first.
Solid line: this model (3,531 kWh). Dashed line: the class median.

UEF 0.92 · Grade G Price it on your ZIP
This model has a UEF, the ratio of hot water delivered to energy used, of 0.92. This site computed its annual energy of 3,531 kWh from that UEF and the DOE test's daily hot-water draw for the medium draw pattern. The registry does not publish that annual figure itself. The source is DOE CCD, retrieved 2026-09-19. Among the 426 models registered as an electric tank at the medium draw pattern, this one ranks 213th lowest for energy use, which places it in the second-lowest quarter of its class. The calculation method is documented on its own page.
The class median is 3,531 kWh, and this model differs from it by 0 kWh, so on energy use alone it sits equal to the median. The figure fits a household whose hot-water use resembles the medium draw pattern, a typical household on a busy morning. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 61 gallons, and its rated volume is 46 gallons. The data here does not say whether those values cover a particular household's peak demand. A household with much heavier or lighter use than the test draw should not read 3,531 kWh as its own annual use. The water heater selector filters by fuel, space and size.
Running cost is not stated in the text because it depends on your own utility electricity tariff. The cost calculator applies the rate for your ZIP to 3,531 kWh, the figure for the medium draw pattern. The result is a calculation at test conditions, not a measured bill, and actual use in your home is not available from the registry. The modeled installed-cost range appears in its own block with its source and date, so this text does not repeat it. To compare units, find a same-class replacement by model number, such as ENS50T-DR***, and read energy use within the same draw pattern.
