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 S33-50TEWH-4500, an electric tank, it uses 3,531 kWh of electricity a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It equals its class median of 3,531 kWh, a difference of 0 kWh, ranking 213th lowest energy use of 426.
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.

The registry does not print the 3,531 kWh figure. This site computes it from two inputs. The first is the UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. The second is the DOE test's daily hot-water draw for the medium pattern. The UEF comes from the DOE CCD, retrieved 2026-09-19. The class is the 426 electric tanks registered at the medium draw pattern. Within it, the 213th rank puts this model in the second-lowest quarter for energy use. Each input and step is explained on the page about how the annual cost is calculated.
The model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 63 gallons. Its rated volume is 45 gallons. The medium draw pattern stands for a typical household with a busy morning of hot-water use. The 3,531 kWh figure applies to a home whose daily use is close to that pattern. This page has no energy figure for a home that draws much more or much less hot water, so that value is not available. A plumber checking fit at a different size can use the selector by fuel, space and size. A seller comparing this unit with others in its class can run a same-class replacement search by model number.
This page does not state a running cost, because the cost depends on your own utility's electricity rate. Multiplying 3,531 kWh by that rate gives the yearly cost at the medium draw pattern. The cost calculator on your own ZIP does this with your local tariff. The model's energy use equals the class median. So at that draw and on the same rate, its running cost matches that of a median unit in the class. Installed price appears in a separate block on this page, with its source and date. That block shows a modeled installed-cost range, not a quote. The registry does not show how much energy the model uses in a real home outside the DOE test, so that figure is unknown.
