VAUGHN MP55F

The 3,531 kWh figure is not printed in the registry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.92 for this model. The second input is the DOE test's daily hot-water draw for the medium pattern. That pattern stands for a typical household with a busy morning. The figure holds only at that test draw. A home that draws more or less hot water each day will use a different amount, and this page does not have that amount. The source is the DOE CCD, retrieved 2026-09-19. Our page on how the annual energy and cost figures are calculated sets out each step.

The MP55F is compared with the 426 models registered as an electric tank at the medium draw pattern. It ranks 213th lowest in energy use among them. Its difference from the class median of 3,531 kWh is 0 kWh, so it sits exactly at the middle of its class. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 58 gallons. Its rated volume is 54 gallons. These ratings match a household whose daily use is close to the medium pattern. They say nothing about a home that routinely needs more than 58 gallons in its busiest hour.

This page does not give a yearly running cost in the text. The cost of 3,531 kWh of electricity depends on your own utility tariff, and tariffs differ by utility and by rate plan. The page therefore works out the cost from your ZIP and does not estimate it. Enter your ZIP in the running cost calculator for your own ZIP to see that cost at the medium draw pattern. The installed price range is shown in its own block, with its source and date. It is a modeled range, not a quote. This page cannot tell how much hot water your home actually uses, so a cost at any other daily draw is unknown here.
