STATE HPTU-66N 1**

3.45 UEF DOE CCD · 2026-09-19
C

Grade C: where this UEF sits among the 194 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

An electric tank, high draw pattern (a larger household, or one where showers and laundry overlap).

At the high draw pattern, the standard daily hot-water usage DOE tests against, the STATE HPTU-66N 1** uses 1,438 kWh of electricity a year. If you are verifying this unit, that is 132 kWh above the 1,306 kWh median for its class. It ranks 135th lowest energy use of 194 electric tanks at that draw pattern.


Energy use per year

1,438 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 above the median of 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 135 of 194, lowest energy first.

This model: 1,438 kWh

Solid line: this model (1,438 kWh). Dashed line: the class median.

What these figures mean

This site calculates the 1,438 kWh figure; the registry does not publish it. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily draw for this pattern. This model's UEF is 3.45, from DOE CCD data retrieved on 2026-09-19. The figure applies only at the federal test's daily draw, not to the actual use of any particular home. A home that uses less hot water than the test would use less energy. A home that uses more would use more. This page does not have data on the size of either difference. The method behind the annual cost figure explains each step of the calculation.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 79 gallons for this model. Its rated volume is 67 gallons. A plumber or seller checking a match can compare these two values with the listing. The 1,438 kWh figure does not apply to a home that uses less than the high pattern. For that kind of home, this page gives no energy figure, because the figure here is for the high draw pattern only. The selector by fuel, space and size groups models by those three factors.

This model is compared with the 194 electric tanks registered at the high draw pattern. For energy use, it falls in the second-highest quarter of that group. If you are checking a replacement, you can compare other models against its 132 kWh gap above the median. The same-class replacement search by model number lists models in the same class. This text gives no running cost, because the cost depends on your utility's electricity rate. Instead, the page calculates it from your ZIP. To see what 1,438 kWh a year costs at your rate, use the cost calculator for your ZIP. The installed price range has its own block on this page, with its source and date.
