AMERICAN STANDARD WATER HEATERS ENS30L-*

0.93 UEF DOE CCD · 2026-09-19
G

Grade 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).

For a second opinion on this unit: the AMERICAN STANDARD WATER HEATERS ENS30L-* uses 2,413 kWh a year at the draw pattern, the standard daily hot-water usage DOE tests against, set to low. That is 26 kWh below the class median of 2,439 kWh, ranking 9th lowest of 163 models.


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.

This model: 2,413 kWh

Solid line: this model (2,413 kWh). Dashed line: the class median.

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.

What these figures mean

The figure of 2,413 kWh is computed by this site, not the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.93 with the DOE test's daily hot-water draw for the low draw pattern. The fuel is electricity, and the source is DOE CCD, retrieved 2026-09-19. The value holds only at that test draw. Actual use in a home depends on how much hot water the household draws, and this page does not measure that. The registry lists this model as an electric tank with a rated volume of 27 gallons.

This model is compared with the 163 models registered as an electric tank at the low draw pattern. Its energy use is 26 kWh below the class median of 2,439 kWh. Its rank of 9th lowest places it in the lowest quarter of its class for energy use. The low draw pattern describes a one- or two-person household. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 44 gallons. The data here do not show results at any other draw pattern, so they say nothing about larger households. To narrow options by fuel, space and size, use the water heater selector.

Running cost is not stated in this text because it depends on your own utility electricity tariff. Multiply 2,413 kWh by your rate per kilowatt-hour, or enter your ZIP in the cost calculator, which does this for you. The calculation method is documented separately. If you are checking a swap, you can find a same-class replacement by model number and compare its energy use with the class median of 2,439 kWh. The installed price range appears in its own block on this page with its source and date. It is a modeled range, not a quote.
