AMERICAN STANDARD WATER HEATERS ENS30T-*

0.92 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).

You are checking AMERICAN STANDARD WATER HEATERS ENS30T-*, an electric tank, and it uses 2,439 kWh a year at the low draw pattern. The low draw pattern, the standard daily hot-water usage DOE tests against, fits a one- or two-person household. The class median is 2,439 kWh, so the difference is 0 kWh.


Energy use per year

2,439 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 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 19 of 163, lowest energy first.

This model: 2,439 kWh

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

This page computes 2,439 kWh for AMERICAN STANDARD WATER HEATERS ENS30T-* from two inputs. The inputs are the registry's UEF of 0.92 and the DOE test's daily hot-water draw for the low draw pattern. UEF, the ratio of hot water delivered to energy used, is a registry value and not a figure computed here. The energy figure is therefore this site's calculation, not a registry entry. The fuel is electricity, and the DOE CCD data was retrieved on 2026-09-19. The figure holds only at the federal test's daily draw. Real use in a home can differ, and this page does not estimate it. The methodology page explains how the annual cost is calculated.

The class for comparison is the 163 models registered as an electric tank at the low draw pattern. The class median is 2,439 kWh, and this model differs from it by 0 kWh. The direction is equal to the median, not above or below it. Its rank is 19th lowest energy use of 163. That places it in the lowest quarter of its class for energy use. Both comparisons are made at the low draw pattern only. Ranks at other draw patterns are not available on this page. To check another unit in the same class, find a same-class replacement by model number.

The rated volume is 27 gallons. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 41 gallons. The 2,439 kWh figure suits a one- or two-person household, the low draw pattern it was computed for. It does not describe a household with a higher daily draw, and this page has no figure for one. Running cost depends on your own electricity rate, so no cost is written here. Enter your ZIP in the cost calculator to apply your utility tariff to 2,439 kWh. The water heater selector filters by fuel, space and size.
