VAUGHN THERMAL MP80F

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.92 for this model. This site computed the annual figure of 5,392 kWh from that UEF. It used the DOE test's daily hot-water draw for the high draw pattern. The registry does not publish the annual figure itself. The comparison class is the 21 models registered as an electric tank your utility can shift to off-peak hours. This model holds 3rd lowest energy use of 21, which is in the lowest quarter of its class. The class median is 5,392 kWh, so the difference from the median is 0 kWh. The energy figure comes from DOE CCD, retrieved 2026-09-19.

The model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 83 gallons. Its rated volume is 80 gallons. The high draw pattern describes a larger household, or one where showers and laundry overlap. So the figure of 5,392 kWh is the relevant one for a home of that kind. It does not describe a household with a lighter draw, and energy use at other draw patterns is not available here. Neither rating changes the annual figure, which comes from the UEF and the draw pattern alone. To compare other fuels, spaces and sizes, use the water heater selector.

Running cost depends on your own utility electricity tariff, so this text states no cost for the MP80F. The cost calculator applies the rate for your ZIP to the 5,392 kWh figure. The methodology page explains how the annual cost is calculated. An installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on. That range is not stretched past its limit. Until a rate is applied, the value that can be checked is 5,392 kWh at the high draw pattern.
