VAUGHN THERMAL ME120HPT

3.38 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).

You are checking the VAUGHN THERMAL ME120HPT, an electric tank tested at the high draw pattern, the standard daily hot-water usage DOE tests against. At that test draw, this site calculates 1,468 kWh of electricity a year. That is 162 kWh above the median of 1,306 kWh for its class.

Energy use per year

1,468 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 158 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 figure of 1,468 kWh 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. It also uses the DOE test's daily hot-water draw for the high draw pattern. The registry lists this model's UEF as 3.38, from the DOE CCD, retrieved 2026-09-19. The figure holds only at that federal test draw. A home that uses more or less hot water will use a different amount of electricity, and that amount is not known here. Among the 194 models registered as an electric tank at the high draw pattern, this model ranks 158th lowest in energy use. That places it in the highest quarter of its class for energy use.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The registry gives this model a first hour rating, the gallons of hot water available in the first hour from a full tank, of 105 gallons. Its rated volume is 109 gallons. These ratings describe hot-water capacity at the test conditions, not the energy use of any one home. The 1,468 kWh figure compares only with other electric tanks at the high draw pattern. A unit with a different fuel or draw pattern belongs to another class, so the 162 kWh gap does not carry over to it. To compare across classes, use the water heater selector by fuel, space and size. To check other electric tanks at this draw pattern, use the same-class replacement search by model number.

This page gives no running cost in the text. The cost of 1,468 kWh a year depends on your own utility's electricity tariff, so the page computes it from your ZIP. The cost calculator on your own ZIP applies your rate to this model's figure. The page on how the annual cost is calculated sets out each step. On a flat rate, the 162 kWh above the class median is billed at that same rate. On a tiered or time-of-use tariff, the effect of that gap is not known from the registry data. 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 the range is not stretched past it.
