AMERICAN STANDARD WATER HEATERS ENS50H-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 verifying this unit, AMERICAN STANDARD WATER HEATERS ENS50H-DR*** uses 3,531 kWh a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 0 kWh from the class median of 3,531 kWh, placing it 213th lowest of 426 electric tank models.
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.

This site computed the figure of 3,531 kWh, not the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.92 with the DOE test's daily hot-water draw for the medium draw pattern. The figure therefore describes an electric tank at that draw only. It is not a measurement from any home. The registry lists 426 electric tanks at this draw pattern, and their median is 3,531 kWh. This model is equal to that median, a difference of 0 kWh. It ranks 213th lowest in energy use, which is the second-lowest quarter of its class. The source is DOE CCD, retrieved 2026-09-19.
The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 67 gallons for this model. The rated volume is 46 gallons. These two values, together with the medium draw pattern, are the basis on which this energy figure applies. A household whose daily hot-water use is close to the medium pattern can compare its own situation with the 3,531 kWh shown. A household with a much larger or smaller daily draw should not read the figure as its own, because energy use at other draw patterns is not available for this model on this page. To compare tanks by fuel, space and size, use the water heater selector. To find a same-class unit by model number, use the replacement finder.
Running cost is not stated in the text because it depends on your own utility electricity rate. The calculation multiplies the 3,531 kWh by that rate, and the rate differs between utilities. The cost calculator applies your ZIP to this model's figure. The methodology page explains how the annual cost is worked out. Because this model sits at the class median of 3,531 kWh, its running cost on any given rate would also be at the class median. Any other model in the class with lower or higher energy use will differ in proportion. The modeled installed-cost range appears in its own block on the page, with its source and date, and is not repeated here.
