AMERICAN STANDARD WATER HEATERS ENS30LU-*
0.93 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, low draw pattern (a one- or two-person household).
Checking AMERICAN STANDARD WATER HEATERS ENS30LU-* against the registry: this electric tank uses 2,413 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That is 26 kWh below the class median of 2,439 kWh among 163 electric tank models registered at the same draw pattern.
Energy use per year
2,413 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 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 9 of 163, lowest energy first.
Solid line: this model (2,413 kWh). Dashed line: the class median.

The figure of 2,413 kWh is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.93 with the daily hot-water draw that the DOE test assigns to the low draw pattern. The source is DOE CCD, retrieved 2026-09-19. The gap to the class median of 2,439 kWh is 26 kWh a year at that draw pattern. Figures for other draw patterns are not available here, and this page does not estimate them. The calculation is described in how the annual cost is calculated.
Among the 163 electric tank models registered at the low draw pattern, this unit has the 9th lowest energy use of 163, which places it in the lowest quarter of its class. The rank compares energy use only and says nothing about capacity. The rated volume is 27 gallons, and the first hour rating, the gallons of hot water available in the first hour from a full tank, is 40 gallons. The figure suits households whose hot-water use matches the low draw pattern. For households with higher daily use, the registry figure does not apply, and the water heater selector filters by fuel, space and size.
Running cost is not stated in the text because it depends on the electricity tariff you pay. The 2,413 kWh figure is a quantity of energy, and it converts to a cost only at your own rate. The cost calculator applies the tariff for your ZIP to this model. The installed price range appears in its own block with its source and date, as a modeled range and not a quote. If you are replacing a unit, you can find a same-class replacement by model number starting from ENS30LU-*. Actual use that differs from the federal test's daily draw will change the annual energy of this unit.
