Checked against the federal registry at DOE's test use, the Whirlpool H18vA857(3B) uses 481 kWh of electricity 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 360 standard-size front-loaders.


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: 139 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 was computed by this site, not the registry. It combines the registry's IMEF with this model's capacity, the drum's volume in cubic feet, of 4.5, at DOE's test use. That test use assumes an electric water heater and an electric dryer, so the figure includes the energy to dry each load. ENERGY STAR files a separate machine-only figure of 139 kWh a year for this model. That figure covers the washer and its electrically heated water alone, with the dryer left out. The difference between 481 kWh and 139 kWh is the dryer's share under the test assumptions. Neither figure is published here for a home with a gas water heater or a gas dryer. The registry values come from DOE CCD, retrieved 2026-10-25, and how the yearly energy and water figures are calculated sets out each step.

Read the rest

The 4,248 gallons figure is also this site's calculation, not a registry value. 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 and by DOE's yearly number of test cycles. The result describes water use at the test level, not any one household's laundry schedule. A cost for the 4,248 gallons is not stated on this page. No free national source publishes local water and sewer rates, so no amount is estimated. The electricity running cost is also left out of this text, because it depends on the reader's own utility tariff. The page computes that cost separately from the reader's ZIP code.

This model is compared with the 360 models registered as front-loading washers of standard size. Its IMEF of 2.76 equals the class median of 2.76, and it ranks 101st highest IMEF of the 360. It is rated above the federal minimum IMEF for its class. Of the 360 models, 37 are rated at that federal minimum. The minimum IMEF value itself is not available in the data behind this page. A higher IMEF means more laundry washed per kilowatt-hour, so this model sits at its class median on that measure. It is also sold under the model names WFW5620H**, WFW6620H**. Other registered models can be checked through all clothes washer pages.
