STATE HPTA-40 2**
3.6 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).
If you are checking the STATE HPTA-40 2**, an electric tank water heater, it uses 902 kWh of electricity a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,629 kWh below its class median of 3,531 kWh, ranking 53rd lowest of 426.
Energy use per year
902 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 53 of 426, lowest energy first.
Solid line: this model (902 kWh). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's rated tank size lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

UEF 3.6 · Grade B Price it on your ZIP
The 902 kWh figure is computed by this site. The registry does not publish it. It 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 draw pattern. For this model the UEF is 3.6, taken from the DOE CCD as retrieved on 2026-09-19. The result holds only at that test draw. A household that uses more hot water each day than the test assumes will use more electricity than 902 kWh. A household that uses less will use less. The registry data does not show how large that difference would be. The full calculation is set out in how the annual cost is calculated.
The comparison covers the 426 models registered as an electric tank at the medium draw pattern. Within that group, this unit's 902 kWh sits 2,629 kWh below the class median of 3,531 kWh, which places it 53rd lowest. Gas and tankless units are in other classes and are not part of this ranking. The model has a rated volume of 36 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 55 gallons. The registry data does not say whether that capacity suits a household whose use differs from the medium draw pattern. To look up a unit from the same class, use the same-class replacement search by model number.
Running cost is not given in this text. It depends on your own utility electricity tariff, so the page works it out from your ZIP and does not assume a rate. The calculation starts from this model's 902 kWh a year at the medium draw pattern and then applies your tariff. You can run it with the cost calculator on your own ZIP. This page does not publish an installed price range for this model. The model's ratings fall outside the range the cost database's model was fitted on, and the page does not stretch that range to cover them. The installed price is therefore unknown here. This page cannot confirm any installed price quoted elsewhere.
