Checking the Whirlpool H24JAJ50(3B)? At DOE's test use, it uses 481 kWh of electricity a year with an electric water heater and an electric dryer, and 4,248 gallons of water. 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: 140 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 with the model's capacity, the drum's volume in cubic feet, which is 4.5 for this washer. The source is DOE's Compliance Certification Database, retrieved 2026-10-25. Because IMEF counts drying energy, that total includes the electric dryer as well as the washer. ENERGY STAR files a separate machine-only figure of 140 kWh a year. That covers the machine and its electrically heated water alone, with the dryer left out. The gap between 481 kWh and 140 kWh is therefore the dryer's modeled share at DOE's test use. As written, neither figure applies to a home with a gas water heater or a gas dryer. The steps are set out in how the yearly energy and water figures are calculated.

Read the rest

Water use follows the same method. IWF, the gallons of water used per cycle for each cubic foot of drum, is 3.2 for this model. Applied to its 4.5 cubic feet at DOE's test use, that gives 4,248 gallons a year. This is a test-use figure, so a household running more or fewer loads will see a different total. The page does not show a cost for that water. No free national source publishes local water and sewer rates, and this site does not estimate one. The electricity running cost is also left out of this text. It depends on the reader's own utility tariff, so the page computes it from the reader's ZIP code instead. The installed-cost range appears in its own block, with its source and date, as a modeled range rather than a quote.

The comparison class is the 360 models registered as front-loading, standard-size washers. This model's IMEF of 2.76 equals the class median of 2.76. Ranked by IMEF, it sits 101st highest of 360. It is rated above the federal minimum IMEF for its class, while 37 models in the class sit at that minimum. The federal minimum value itself is not available in this data. The registry lists this record as sold under the model numbers WFW4720R**, WFW5220R**, so those names share the same rated values. Other washers in the class can be checked from all clothes washer pages.
