Checking the Maytag H18vB844(3B)? At DOE's test use, this washer draws 481 kWh a year with an electric water heater and an electric dryer. It uses 4,248 gallons of water a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.76, equal to the median of its class.


Energy and water per year

481 kWh a year with an electric water heater and an electric dryer

Computed by this site from the registry's IMEF and drum capacity at DOE's test use of 295 cycles a year. IMEF counts the washer, heating its water electrically, and the electric dryer's work on what the spin leaves wet — so this is the total for that kind of home. How it is calculated

The machine and its hot water alone, dryer not included: 128 kWh a year, as ENERGY STAR files it.

Not published: A home with a gas water heater, a gas dryer or line drying

DOE's rating assumes electric water heating and an electric dryer and files no split between the machine, the water heating and the drying.

Such a home uses less electricity than the total above; how much less, no registry says for this model.

4,248 gallons of water a year

Computed from the registry's IWF and drum capacity at the same 295 cycles a year.

Not published: What the water costs

water and sewer rates are set by thousands of local utilities and no free national source publishes them.

The gallons above are the figure to multiply by your own water and sewer rate.

This model is rated above the federal minimum IMEF for its class.

Service life: DOE’s cost database assumes 11 years for front-loading washers. That is a class assumption, not this model’s rating or a warranty — no registry publishes either.

What these figures mean

This site calculated the 481 kWh figure; the registry does not publish it. It combines the registry's IMEF of 2.76 with the model's capacity, the drum's volume in cubic feet, which is 4.5. The calculation assumes DOE's test use, the yearly cycle count set in the test procedure. Its scope is the washer with an electric water heater and an electric dryer, so the dryer's energy is inside this total. ENERGY STAR files a separate machine-only figure of 128 kWh a year. That figure counts only the machine and the energy to heat its water electrically, without the dryer. The dryer's share lies in the difference between the two. However, the two figures come from different sources, so they are not one calculation. The DOE CCD data behind the larger figure was retrieved on 2026-10-25. The method page explains how the yearly energy and water figures are calculated.

Read the rest

This site also calculated the yearly water figure of 4,248 gallons. It uses the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, which is 3.2 for this model. That factor is multiplied by the 4.5 cubic foot capacity at DOE's test use. The registry lists this model as sold under MHW5630H**, and the same figures apply to that listing. The page does not show a water cost for the 4,248 gallons. No free national source publishes local water and sewer rates, so any cost shown would be an estimate. A reader who knows their local rate per gallon can apply it to the 4,248 gallons directly. How often the machine runs in a given home is not in this data.

Among the 360 models registered as front-loading washers of standard size, this model's IMEF of 2.76 equals the class median of 2.76. In that class it ranks 101st highest IMEF of 360. It is rated above the federal minimum IMEF for its class, while 37 models in the class sit at that minimum. This data does not include the minimum value itself. The text does not state a running cost for the 481 kWh, because the cost depends on the reader's own utility electricity tariff. The page calculates it from the reader's ZIP instead. The installed price range has its own block, with its source and date. It is a modeled range, not a quote. Other washers registered in the same way are listed on all clothes washer pages.
