STATE PETX-40 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 verifying the STATE PETX-40 1**, 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 is equal to the median of the 426 electric tank models registered at that pattern, a difference of 0 kWh.
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 calculated the 3,531 kWh figure; it is not taken from the registry. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, and the daily hot-water draw that the DOE test sets for the medium pattern. This model's UEF is 0.92. The source is the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The figure holds only at that test draw. A household that draws more hot water each day would use more electricity, and one that draws less would use less. The steps that turn this figure into a yearly cost are explained in how the annual cost is calculated.
Within its class, the STATE PETX-40 1** ranks 213th lowest in energy use of 426 models. Because its figure equals the class median, a same-class unit below the median uses less electricity at the same test draw. A unit above the median uses more. The tank has a rated volume of 37 gallons. It also has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 64 gallons. A household whose busiest hour needs more than 64 gallons is outside what this rating covers. A plumber matching an existing unit can find a same-class replacement by model number.
The running cost is not stated in this text because it depends on your own utility's electricity tariff. The page applies the rate for your ZIP to the 3,531 kWh test-draw figure. Readers who check the same PETX-40 1** in different utility areas will therefore see different costs for the same energy use. The cost calculator on your own ZIP shows that figure. The page shows the installed-cost range in a separate block, with its source and date. That range is modeled, not a quote. The registry does not give this model's energy use under your household's actual daily draw, so that figure is not available.
