Midea MEWH40T82S1

The 3,531 kWh figure does not appear in the registry itself. This site computed it from the model's UEF, the ratio of hot water delivered to energy used, which is 0.92 here. That ratio was applied to the daily hot-water draw the DOE test sets for the medium pattern. The medium pattern stands for a typical household of a few people on a busy morning. The UEF comes from the DOE Compliance Certification Database, retrieved 2026-09-19. The annual figure therefore holds only at the test's draw. The registry gives no energy value for this model at any other usage level, so that value is not available here. The steps behind the annual cost calculation are published separately.

This Midea MEWH40T82S1 is an electric tank with a rated volume of 37 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 55 gallons. The model was tested at the medium draw pattern, so its annual figure applies most directly to a household whose busiest morning resembles that test. A household that needs more than 55 gallons within an hour asks more than this rating covers. The registry holds no high-draw test result for this model, so its energy use at a heavier pattern is unknown. Models using another fuel sit outside this comparison class. The selector by fuel, space and size lists models across those groups.

The comparison class is the 426 models registered as an electric tank at the medium draw pattern. This model's annual use equals the class median of 3,531 kWh, a difference of 0 kWh. Its rank is 213th lowest in energy use of 426, which places it at the middle of the class. The running cost is not stated in this text because it depends on your own utility's electricity rate. The cost calculator for your ZIP applies your tariff to the 3,531 kWh figure. The installed-price range on this page is a modeled range with its own source and date, not a quote.
