Midea MEWH28L82S1

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).

If you are checking the Midea MEWH28L82S1, an electric tank, it uses 2,439 kWh of electricity a year. That figure applies to the low draw pattern, the standard daily hot-water usage DOE tests against. It sits 0 kWh from its class median of 2,439 kWh, so it is equal to the median.


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

What it costs to install

Not published: Installed cost range

This model's rated tank size 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.

What these figures mean

The 2,439 kWh figure does not appear in the registry itself. This site calculated it from the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the low pattern. For this model the UEF is 0.92. The result is valid only at that test draw. It does not describe a household whose daily hot-water use differs from the test. The registry also lists a rated volume of 26 gallons. It also gives a first hour rating, the gallons of hot water available in the first hour from a full tank, of 45 gallons. The underlying data comes from DOE CCD, retrieved 2026-09-19. The page on how the annual energy and cost figures are calculated sets out each step.

The comparison class is the 163 models registered as an electric tank at the low draw pattern. Their median is 2,439 kWh a year, and this model differs from it by 0 kWh. Its rank is 19th lowest energy use of 163, which places it in the lowest quarter of its class. The class data here does not show how many models share the median figure. So this page cannot explain how a model at the median also ranks in the lowest quarter. The low draw pattern models the use of a one- or two-person household, and the 2,439 kWh figure covers only that use. For a household whose use matches a higher draw pattern, this figure does not apply. To compare other registered models, use the tool that lets you find a same-class replacement by model number.

This text gives no running cost. The cost depends on your own utility's electricity tariff, which varies by location. The page calculates it from your ZIP, using 2,439 kWh a year at the low draw pattern. The running-cost calculator for your own ZIP shows that result. An installed price range for the MEWH28L82S1 is not available. Its ratings fall outside the range the cost database's model was fitted on, and this site does not extend that range. If you are verifying a quote, the running cost depends on your rate. The installed price is not available on this page. The figures that can be checked here are the UEF of 0.92, the 45-gallon first hour rating and the 2,439 kWh yearly energy use.
