Midea MEWH30S82S1
0.92 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).
If you are checking the Midea MEWH30S82S1, this site computes 2,439 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That equals the class median of 2,439 kWh, a difference of 0 kWh, among 163 registered electric tank models.
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.
Solid line: this model (2,439 kWh). Dashed line: the class median.

The Midea MEWH30S82S1 is an electric tank heater, and its annual figure of 2,439 kWh applies only to the low draw pattern. This site calculated it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model, and from the DOE test's daily hot-water draw for that pattern. The registry does not publish the annual figure itself. Among the 163 electric tank models registered at the low draw pattern, this model ranks 19th lowest for energy use and sits in the lowest quarter of its class. The class median is 2,439 kWh, so the difference is 0 kWh. The source is DOE CCD, retrieved 2026-09-19, and the steps are explained in how the annual cost is calculated.
The figure suits a household whose hot-water use matches the low draw pattern. The tank has a rated volume of 28 gallons, and its first hour rating, the gallons of hot water available in the first hour from a full tank, is 47 gallons. Those two values are the ones to compare with your own peak demand. A household that uses more hot water than the low draw pattern should not read 2,439 kWh as its own consumption. This site has not computed the model for other draw patterns, so that value is not available here. The water heater selector by fuel, space and size can help if your requirements differ.
The running cost is not written in this text because it depends on your own utility electricity tariff. The calculation is 2,439 kWh multiplied by your rate per kilowatt-hour, and it holds only for the low draw pattern. The cost calculator on your own ZIP applies that rate for you. At any single rate, this model would cost the same to run as a model at the class median of 2,439 kWh, because the difference is 0 kWh. The modeled installed-cost range has its own block with a source and date, and it is not repeated here. To look for a same-class unit, you can find a replacement by model number starting from MEWH30S82S1. The figures come from the federal test's daily draw, not from metered use in a specific home, which is unknown.
