STATE FPTU-50 1**
3.35 UEF DOE CCD · 2026-09-19Grade B: 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).
The STATE FPTU-50 1** uses 970 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. If you are checking this figure, it sits 2,561 kWh below the 3,531 kWh median of the 426 electric tank models at that pattern. That places it 101st lowest of 426 for energy use.
Energy use per year
970 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 below the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 101 of 426, lowest energy first.
Solid line: this model (970 kWh). Dashed line: the class median.

UEF 3.35 · Grade B Price it on your ZIP
This site computed the 970 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 medium pattern. This model's UEF is 3.35, taken from the DOE CCD, retrieved 2026-09-19. The result holds only at that test draw. A household that draws more hot water each day would use more than 970 kWh, and one that draws less would use less. How much more or less is not available, because the data gives no figure for other draws. The steps behind the figure are set out in how the annual energy and cost figures are calculated.
Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 66 gallons. The rated volume is 46 gallons. DOE uses the medium draw pattern to represent a typical mid-sized household, so the 970 kWh figure matches that kind of home most closely. A household whose busiest hour stays within 66 gallons is inside the conditions the test assumes. The 101st place among 426 models applies only to that same pattern. This data does not show whether the unit fits a given space or electrical supply. To compare it with other units by fuel, space and size, use the water heater selector by fuel, space and size.
A household that regularly needs more than 66 gallons in its busiest hour is outside the medium pattern. For that household, neither the 970 kWh figure nor the 2,561 kWh gap to the class median applies as stated. The running cost is not written here either. It depends on your own utility's electricity tariff, and this page does not hold that tariff. Instead, the page applies your ZIP code's rate to 970 kWh in the running-cost calculator for your ZIP. The installed price range appears in its own block, with its source and date. It is a modeled range, not a quote.
