U.S. CRAFTMASTER 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).

If you are checking U.S. CRAFTMASTER HPTU-66N 1** against its registry entry: it uses 1,438 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 132 kWh above the 1,306 kWh median of 194 electric tank models.


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

The figure of 1,438 kWh was computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 3.45 with the DOE test's daily hot-water draw for the high draw pattern. It is a test-condition value. A household's actual use can differ, and the registry does not supply a measured value for any particular home. Against the class median of 1,306 kWh, this model sits 132 kWh higher. It ranks 135th lowest in energy use among 194 models, which places it in the second-highest quarter of its class for energy use. The source is DOE CCD, retrieved 2026-09-19.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The figure of 1,438 kWh applies to that pattern only. A household that fits it can compare this model directly with the other 194 in the class. A household with a smaller daily draw cannot read the figure as its own, and the registry gives no value for other patterns here. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 79 gallons, and the rated volume is 67 gallons. Anyone who ranks models by energy use alone will find 135th lowest of 194 in this class. To filter by fuel, space and size, use the water heater selector, or look up a same-class model with replacement by model number.

The running cost is not stated in the text because it depends on your own utility electricity rate. The calculation multiplies 1,438 kWh by that rate, so the 132 kWh gap to the class median scales with the same rate. The cost calculator does this from your ZIP. The steps behind the annual cost are described in the water heater methodology. The modeled installed-cost range appears in its own block on this page, with its source and date. It is a modeled range, not a quote, and it is not repeated here. The registry does not report the hot-water use of your household, so the result reflects the federal test's draw and nothing more.
