RELIANCE WATER HEATERS HETF-50 1**
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 RELIANCE WATER HEATERS HETF-50 1**, this electric tank 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 sits 0 kWh from the class median of 3,531 kWh, ranking 213th lowest energy use of 426 comparable models.
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.

This site computed the 3,531 kWh figure; the registry does not publish it. The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.92 for this model. This site combines that UEF with the DOE test's daily hot-water draw for the medium draw pattern, using DOE CCD data retrieved 2026-09-19. The page on how the annual cost is calculated sets out each step. The figure holds only at the test's daily draw. A household that uses more or less hot water than that draw will use a different amount of electricity. That amount is not available in this data. The class comparison uses the same test condition for all 426 models.
The listing places this model at the medium draw pattern, which DOE uses for typical household hot-water use. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 74 gallons. That rating comes from a rated volume of 45 gallons. A plumber or seller can check those gallons against the label on the unit being replaced. The tool to find a same-class replacement by model number lists other electric tanks at the same draw pattern. A household that needs more than 74 gallons in its busiest hour needs more than this rating covers. This data has no figure for this model at a heavier draw pattern. For a different fuel or tank size, the selector by fuel, space and size filters the wider registry.
The running cost is not stated in this text because it depends on your own utility's electricity tariff. The page computes it from your ZIP by applying that rate to 3,531 kWh a year at the medium draw pattern. The cost calculator on your own ZIP shows the result. This model's energy use equals the class median of 3,531 kWh. So at the test draw and the same rate, its running cost matches that of a median model in its class. A model using less than 3,531 kWh costs less at that rate, and a model using more costs more. The installed price range appears in its own block with its source and date. It is a modeled range, not a quote.
