U.S. CRAFTMASTER ENL-40 1**
0.89 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 this U.S. CRAFTMASTER ENL-40 1**? At the low draw pattern, the standard daily hot-water usage DOE tests against, this electric tank uses 2,522 kWh a year. That is 83 kWh above the class median of 2,439 kWh and ranks 143rd lowest of 163.
Energy use per year
2,522 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 above the median of 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 143 of 163, lowest energy first.
Solid line: this model (2,522 kWh). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's UEF lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
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.

UEF 0.89 · Grade G Price it on your ZIP
The figure of 2,522 kWh is computed by this site, not published by the registry. The inputs are the registry's UEF, the ratio of hot water delivered to energy used, which is 0.89 for this model, and the DOE test's daily hot-water draw. That draw is the one for the low draw pattern, meant for a one- or two-person household. The source is DOE CCD, retrieved 2026-09-19. The result holds only at that test draw. A household with different hot-water use is not covered by this figure, and no estimate for it is available.
The data place this model in the highest quarter of its class for energy use, ranked 143rd lowest of 163. The models ranked before it use less energy per year at the same test draw. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 50 gallons. Its rated volume is 35 gallons. The registry data on this page do not show whether those ratings meet a particular household's needs. To compare by fuel, space and size, use the water heater selector. To look up a same-class model, find a replacement by model number.
The running cost of this model depends on the reader's own electricity tariff, so this page states no cost figure and does not estimate one. The cost calculator applies the rate for your ZIP to the 2,522 kWh figure. The method used to calculate the annual cost is documented separately. The 83 kWh gap to the class median is also an energy difference, and its cost depends on the same rate. An installed price range is not published: this model's ratings, including its first hour rating of 50 gallons and rated volume of 35 gallons, lie outside the range the cost database's model was fitted on.
