AMERICAN MHE6-30H-045D 1**

0.9 UEF DOE CCD · 2026-09-19
G

Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

An electric tank, low draw pattern (a one- or two-person household).

You are verifying a model's yearly energy figure. AMERICAN MHE6-30H-045D 1** uses 2,494 kWh a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That is 55 kWh above the class median of 2,439 kWh among 163 electric tank models at that draw pattern.


Energy use per year

2,494 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 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 122 of 163, lowest energy first.

This model: 2,494 kWh

Solid line: this model (2,494 kWh). Dashed line: the class median.

What it costs to install

Not published: Installed cost range

This model's UEF 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 2,494 kWh figure is electricity use for a year at the low draw pattern. The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.9 for this model. This site, not the registry, computed the yearly figure from that UEF and the DOE test's daily hot-water draw. A household that draws more or less hot water than the test assumes will use a different amount. The methodology page sets out how the annual cost is calculated. The energy figure comes from DOE CCD, retrieved on 2026-09-19. It covers electricity only, since this is an electric tank.

Among the 163 electric tank models at the low draw pattern, this model ranks 122nd lowest in energy use. Its 2,494 kWh is 55 kWh above the class median of 2,439 kWh. That places it in the higher-energy part of its class, so it does not suit a reader whose priority is the lowest energy use at this draw pattern. It suits a reader who needs its listed ratings. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 50 gallons. The rated volume is 27 gallons. The water heater selector compares models by fuel, space and size.

Running cost is not stated here, because it depends on your own utility electricity tariff. Multiply 2,494 kWh by your rate per kilowatt-hour, or use the cost calculator to compute it from your ZIP. An installed price range is not published for this model. Its ratings lie outside the range that the cost database's model was fitted on. The range is not stretched past it.
