VAUGHN THERMAL MP45F
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 VAUGHN THERMAL MP45F, this electric tank uses 3,531 kWh of electricity a year. That figure applies at the medium draw pattern, the standard daily hot-water usage DOE tests against. It is 0 kWh from its class median of 3,531 kWh, and it ranks 213th lowest in energy use of 426 models.
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.

The 3,531 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. This model's UEF is 0.92, as listed in the DOE CCD, retrieved 2026-09-19. The class comparison applies the same method to all 426 models registered as an electric tank at the medium draw pattern. The class median is 3,531 kWh, and this model's difference from it is 0 kWh. Its rank of 213th lowest in energy use therefore places it at the class median. The steps behind the figure are set out in how the annual energy and cost are calculated.
This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 57 gallons. Its rated volume is 44 gallons. The 3,531 kWh figure holds only for the medium draw pattern, which DOE uses to represent a typical household's busy-morning demand. A household whose hot-water use is close to that pattern can use the figure as a reference point. A household that draws much more or much less each day will use a different amount of energy. That amount is not available here, because the registry does not report this model's energy use at other draw levels. To compare units by fuel type, available space and tank size, use the water heater selector by fuel, space and size.
The text on this page does not state a running cost. The cost of 3,531 kWh of electricity depends on your own utility tariff. The page computes that cost from your ZIP code, and the result applies only to your rate. On a different tariff, the same 3,531 kWh gives a different result. This model sits 0 kWh from the class median of 3,531 kWh. So on the same rate, a model in this class at the median would have the same running cost. The modeled installed-cost range appears in its own block with its source and date, and it is not a quote. To check another unit in this class, find a same-class replacement by model number, or open the cost calculator for your own ZIP.
