STATE 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).

If you are checking the STATE MHE6-30H-045D 1**, it uses 2,494 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That is 55 kWh above the 2,439 kWh median of the 163 electric tank models registered at the low 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 comes from this site's own calculation. The registry does not publish it. 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 low pattern. This model's UEF is 0.9, and its fuel is electricity. Under the federal test, the low pattern represents a small household's daily hot-water use. The step from UEF to yearly energy is set out in how the annual energy and cost figures are calculated. The figure applies only at that test draw. A household that draws more or less hot water each day will use a different amount. The registry gives no figure for other draw levels. The source is the DOE CCD, retrieved 2026-09-19.

Among the 163 electric tank models registered at the low draw pattern, the MHE6-30H-045D 1** ranks 122nd for lowest energy use. Its 2,494 kWh is 55 kWh above the class median of 2,439 kWh. Being above the median means that, at the same test draw, it is rated to use more electricity than the middle model in its class. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 50 gallons from a rated volume of 27 gallons. This comparison fits a small household whose use matches the low pattern. It does not cover a household that uses more hot water than that pattern. To see registered models in the same class, use find a same-class replacement by model number.

This text does not state a running cost. The cost depends on your own utility's electricity tariff applied to the 2,494 kWh yearly figure at the low draw pattern. The cost calculator for your own ZIP applies your local rate to that figure. The same rate also prices the 55 kWh gap above the class median. No installed price range is published for the MHE6-30H-045D 1**. Its ratings, including its UEF of 0.9 and first hour rating of 50 gallons, fall outside the range the cost database's model was fitted on. The site does not stretch that range to cover this model. So the installed price for this model is not available on this page.
