To verify this washer's registry figures: at DOE's test use, the Maytag H18vB847(3B) uses 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

The 481 kWh figure covers the washer itself, heating its water in an electric water heater, and an electric dryer removing the moisture left after the spin. This site computed it, not the registry. It uses the IMEF and the capacity, the drum's volume in cubic feet, of 4.5, at DOE's test use. Those inputs come from the DOE Compliance Certification Database, retrieved 2026-10-25. ENERGY STAR files a separate figure of 128 kWh a year. That figure covers the machine and its electrically heated water alone, with the dryer not included. The two figures differ mainly in whether the dryer is counted. They come from different sources, so their difference is not an exact dryer figure. The calculation behind the yearly energy and water figures is explained on the methodology page.

Read the rest

The 4,248 gallons a year comes from the IWF, the gallons of water used per cycle for each cubic foot of drum. For this model the IWF is 3.2. This site multiplied it by the 4.5 cubic-foot drum and DOE's yearly test cycle count. The result holds for DOE's test use only. A household running more or fewer loads will use a different amount. What that water costs is not stated here. No free national source publishes local water and sewer rates, so any cost figure would be an estimate. The electricity cost is also absent from this text. It depends on the reader's own utility tariff, so the page computes it from the reader's ZIP instead.

Among the 360 models registered as front-loading, standard size, the median IMEF is 2.76. This model's IMEF of 2.76 equals that median. It ranks 101st by IMEF in the class, counting from the highest. It is rated above the federal minimum IMEF for its class, where 37 models sit exactly at that minimum. The registry lists this model as sold as MHW5630H**. The installed price shown on this page is a modeled range with its own source and date, not a quote. Other models in this class can be checked through the full list of clothes washer pages.
