Midea MEWH38L82S1

0.92 UEF DOE CCD · 2026-09-19
G

Grade 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 checking the Midea MEWH38L82S1, it uses 3,531 kWh of electricity a year at the medium draw pattern. A draw pattern is the standard daily hot-water usage DOE tests against, and the medium one reflects a typical household. This model's figure is 0 kWh away from the 3,531 kWh class median for 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.

This model: 3,531 kWh

Solid line: this model (3,531 kWh). Dashed line: the class median.

What these figures mean

This site calculates the 3,531 kWh per year. The registry does not publish it. The calculation combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium draw pattern. For the MEWH38L82S1, the UEF is 0.92. The source is the DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw. A home that draws more hot water than the medium pattern will use more electricity than 3,531 kWh, and a home that draws less will use less. The registry data does not show how far your own use differs from the test. The steps behind the calculation are set out in how this site calculates annual energy and cost.

The class has 426 models registered as an electric tank at the medium draw pattern. Among them, the MEWH38L82S1 ranks 213th lowest in energy use. It is 0 kWh away from the class median of 3,531 kWh, so its annual energy use at the test draw equals the median. This comparison covers annual energy use only. The unit's first hour rating is 54 gallons, from a rated volume of 35 gallons. First hour rating means the gallons of hot water available in the first hour from a full tank. The unit fits a household whose busiest hour uses no more than 54 gallons. A household that needs more than 54 gallons in its busiest hour needs more than this rating covers. You can list models in the same class with a same-class replacement search by model number.

The text on this page does not give a running cost. The cost of 3,531 kWh a year at the medium draw pattern depends on your own utility's electricity tariff. The page calculates it from your ZIP in a separate block. The cost calculator for your own ZIP runs the same calculation if you want to check another ZIP. The installed price range appears in its own block with its source and date. It is a modeled installed-cost range, not a quote, and this text does not restate it. Both the running cost and the 3,531 kWh figure assume the federal test's medium draw. This data does not show your home's actual yearly electricity use, so a bill may differ from either figure.
