Stream 33 MEWH50S82S1
0.92 UEF DOE CCD · 2026-09-19Grade 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 Stream 33 MEWH50S82S1, it uses 3,531 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 0 kWh from the median of 3,531 kWh for the 426 electric tank models tested at the same pattern. It ranks 213th lowest in energy use.
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.
Solid line: this model (3,531 kWh). Dashed line: the class median.

UEF 0.92 · Grade G Price it on your ZIP
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. The other input is the DOE test's daily hot-water draw for the medium pattern. The UEF comes from DOE CCD, retrieved 2026-09-19. Because the test fixes the daily draw, the figure describes the unit under test conditions, not in a particular home. The UEF of 0.92 is the only input that belongs to this model. So any electric tank at the medium pattern with the same UEF would show the same annual figure. That is why this model's 213th place of 426 depends only on its UEF.
The medium draw pattern stands for a typical household of several people with a busy morning. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 64 gallons. Its rated volume is 47 gallons. The data does not show how closely any real home matches the test's daily draw. A household that uses more hot water each day than the test assumes will use more electricity than 3,531 kWh. If you need another fuel or size, the selector by fuel, space and size lists other classes. To compare against models in the same class, use the same-class replacement lookup by model number.
This page does not state a running cost because the cost depends on your own utility electricity tariff. The yearly cost is 3,531 kWh multiplied by your rate per kWh, at the test's draw. The cost calculator for your own ZIP does that step using your local rate. The page on how the annual cost is calculated sets out each input and its source. This model's use sits 0 kWh from the class median. On any single rate, its test-draw running cost therefore matches that of a class-median unit. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote.
