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).

You are checking the Midea MEWH30T82S1, an electric tank. It uses 2,439 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against. Low fits a one- or two-person household. That is 0 kWh from its class median of 2,439 kWh, so it equals 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 these figures mean

This site calculates the 2,439 kWh figure. 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 low draw pattern. This model's UEF is 0.92. The inputs come from the DOE CCD and were retrieved on 2026-09-19. The figure applies only at the federal test's daily draw. The UEF of 0.92 is a test result, so the 2,439 kWh figure carries the test's conditions, not the use of any single home. The fuel is electricity throughout because the unit is an electric tank.

Its class is the 163 models registered as an electric tank at the low draw pattern. Among those 163 models, it ranks 19th lowest for energy use, which puts it in the lowest quarter of its class. Its 2,439 kWh is 0 kWh from the class median of 2,439 kWh, so it equals the median. This model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 47 gallons. Its rated volume is 28 gallons. The energy figure applies to the one- or two-person household that the low pattern represents. A larger household falls outside that test condition, and this data gives no energy figure for it. To check other units in the same class, find a same-class replacement by model number.

This page states no running cost because that cost depends on your own utility electricity tariff. The page calculates it from your ZIP in the cost calculator on your own ZIP. The page knows this model's energy use: 2,439 kWh of electricity at the low draw pattern. Your rate is unknown until you enter your ZIP. The steps are set out in how the annual cost is calculated. If you compare a cost figure from somewhere else, check that it uses the same condition: the low draw pattern at the federal test's daily draw. A figure based on a different draw pattern cannot be compared with 2,439 kWh. The installed price range has its own block with its source and date. It is a modeled range of installed costs, not a quote.
