VAUGHN THERMAL MP120F-RC

3.75 UEF DOE CCD · 2026-09-19
C

Grade C: where this UEF sits among the 194 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

An electric tank, high draw pattern (a larger household, or one where showers and laundry overlap).

If you are checking the VAUGHN THERMAL MP120F-RC, it uses 1,323 kWh of electricity a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 17 kWh above the 1,306 kWh median for the 194 electric tank models registered at the same draw pattern.

Energy use per year

1,323 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 above the median of 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 99 of 194, lowest energy first.

What it costs to install

Not published: Installed cost range

This model's rated tank size lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.

The annual energy figure on this page does not depend on this range and is unaffected.

Safety record

No CPSC recall names this model.

Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

What these figures mean

The 1,323 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 high draw pattern. The registry lists this model's UEF as 3.75. The figure holds only at that federal test draw. Energy use at any other daily draw is not available here. The source is the DOE CCD, retrieved 2026-09-19. Among the 194 models in its class, this unit ranks 99th lowest for energy use. That places it in the second-highest quarter of its class. The steps behind the figure are set out in how this site calculates annual energy and running cost.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. That is the usage this model was tested against. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 121 gallons. Its rated volume is 119 gallons. A plumber or seller checking a quote can match these two values and the UEF of 3.75 against the registry listing. For a household whose use fits the high draw pattern, 1,323 kWh a year is the relevant figure to compare. Other units can be compared in the water heater selector by fuel, space and size.

For a household with lower hot-water use, the 1,323 kWh figure does not describe expected use, because it assumes the high draw pattern's daily volume. Within its own class, this unit sits 17 kWh above the 1,306 kWh median. Models below that median use less energy at the same test draw. They can be found through a same-class replacement search by model number. Running cost is not stated in this text. It depends on your own utility electricity tariff, so the page computes it from your ZIP in the running-cost calculator for your ZIP. An installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and that range is not stretched past it.
