VAUGHN THERMAL MP55FHPT
3.3 UEF DOE CCD · 2026-09-19Grade B: 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 THERMAL MP55FHPT against the registry, here is its annual energy use. This site calculates 984 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,547 kWh below the class median of 3,531 kWh, ranking 109th lowest of 426.
Energy use per year
984 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 below the median of 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 109 of 426, lowest energy first.
Solid line: this model (984 kWh). Dashed line: the class median.

UEF 3.3 · Grade B Price it on your ZIP
The 984 kWh figure does not appear in the registry itself. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, and from the DOE test's daily hot-water draw for the medium pattern. The UEF listed for this model is 3.3. The inputs come from the DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw, so it does not describe a household with a different daily hot-water use. The comparison class is the 426 models registered as an electric tank at the medium draw pattern. Their median is 3,531 kWh a year, and this model sits 2,547 kWh below it under the same test condition. The page on how the annual figure is calculated sets out each step of that method.
Energy use and sizing are separate checks. The registry lists a rated volume of 55 gallons for this model. It also lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 62 gallons. The medium draw pattern stands for a typical family household with a busy morning peak. A household of that kind matches the condition behind the 984 kWh figure. A household with heavier daily use falls outside that condition, and this page has no annual figure for it. Such a household can compare other units in the water heater selector by fuel, space and size. The ranking of 109th of 426 also applies only within the medium draw pattern class.
The running cost is not stated in this text. It depends on the electricity rate in your own utility tariff, and this page does not estimate that rate. Instead, the page calculates the cost from your ZIP, starting from 984 kWh a year at the medium draw pattern. The running cost calculator for your ZIP shows that result. At a single flat rate, the cost gap against the class median follows the energy gap of 2,547 kWh. Under a tiered or time-based tariff, that relation is not known from the registry data. The installed-cost range appears in its own block on this page, with its source and date. It is a modeled range, not a quote.
