VAUGHN 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 checking the VAUGHN 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 equals its class median of 3,531 kWh, a difference of 0 kWh, and ranks 213th lowest of 426 medium-draw electric tanks.
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.

UEF 0.92 · Grade G Price it on your ZIP
The 3,531 kWh figure is computed by this site, not published by the registry. 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 pattern. For the MP45F, the UEF is 0.92, taken from the DOE Compliance Certification Database retrieved 2026-09-19. The figure therefore holds only at the federal test's daily draw. A household that uses more or less hot water than the medium pattern will use a different amount of electricity. How much different is not available from the registry data on this page. The steps behind the number are set out in how this site calculates annual energy and cost.
Within its class of 426 models registered as an electric tank at the medium draw pattern, the MP45F sits at the median. Its 3,531 kWh matches the class median of 3,531 kWh, a difference of 0 kWh. It ranks 213th lowest in energy use, in the second-lowest quarter of the class. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 57 gallons, from a rated volume of 44 gallons. These figures describe a household whose daily use matches the medium pattern. They do not describe a home whose hot-water use regularly exceeds that pattern. To compare other models in the same class, use the same-class replacement search by model number.
This text states no running cost for the MP45F. Cost depends on your own utility electricity tariff. The page therefore computes it from your ZIP code, applying your rate to the 3,531 kWh figure at the medium draw pattern. You can run the same calculation in the water heater cost calculator for your ZIP. The installed price shown in its own block is a modeled range with its source and date. It is not a quote for any specific installation. Actual energy use in a particular home is not available from the registry; only the test-based figure is. A second opinion on this unit can rest on its UEF of 0.92 and its position in the class.
