STATE HPTS-66 2**

3.7 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).

You are checking a model against the registry. STATE HPTS-66 2** uses 1,341 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 35 kWh above the class median of 1,306 kWh. It ranks 101st lowest of 194 models.


Energy use per year

1,341 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 101 of 194, lowest energy first.

This model: 1,341 kWh

What these figures mean

The registry lists this model's UEF, the ratio of hot water delivered to energy used, as 3.7. This site combined that UEF with the DOE test's daily hot-water draw for the high draw pattern. The result is 1,341 kWh a year of electricity for the high draw pattern. The registry does not publish this annual figure itself. The energy data come from the DOE CCD, retrieved 2026-09-19. The steps are described under how the annual cost is calculated. Both inputs are set by the registry and the test, so the figure is a calculation and not a metered reading. It applies only to that test draw, so a household's actual use can differ.

Among the 194 models registered as an electric tank at the high draw pattern, the class median is 1,306 kWh a year. This model uses 35 kWh more than that median. Its rank is 101st lowest energy use of 194, which puts it in the second-highest quarter of its class for energy use. A larger rank number means higher energy use within this class. The comparison covers annual energy at the test draw only. It is not a comparison with gas or heat pump models. The registry data do not say how the unit performs in a particular home.

The high draw pattern describes a larger household, or one where showers and laundry overlap. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 82 gallons. Its rated volume is 67 gallons. Whether those figures suit a home depends on that home's own hot-water demand, which this page does not measure. Running cost depends on the electricity rate you pay, so it is not stated in the text. Use the cost calculator for your own ZIP to apply your rate to 1,341 kWh. A same-class replacement by model number can be looked up separately.
