Checking the Whirlpool V24aAW51(3B)? With an electric water heater and an electric dryer, it uses 864 kWh a year at DOE's test use, plus 8,820 gallons of water. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 1.57, equal to the class median of 1.57.
Energy and water per year
864 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
Not published: The washer's own share, without the dryer
DOE's database files IMEF, which folds the dryer in; only ENERGY STAR splits the machine out, and it lists this model under no matching rating.
The total above, and the IMEF it comes from, stand as filed.
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.
8,821 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 exactly at the federal minimum IMEF for its class, like many others; no rank is claimed inside that tie.
What you can do. Federal minimum means this model uses as much energy as the law allows for its class. 218 washers in the same class file a higher IMEF; at the same drum size and use, a higher IMEF is less energy a year. See the most efficient washers in each class

Installed cost and service life
Not published: Installed cost range
NLR REMDB's cost model needs the washer's own yearly energy use, which only ENERGY STAR files — and it lists no matching rating for this model.
Ask retailers or installers for a written quote that names this model number. The yearly energy, water and running cost on this page do not depend on it.
Service life: DOE’s cost database assumes 11 years for top-loading washers. That is a class assumption, not this model’s rating or a warranty — no registry publishes either.

The figure of 864 kWh was computed by this site, not the registry. It uses the registry's IMEF of 1.57 and a capacity, the drum's volume in cubic feet, of 4.6, at DOE's test use, with an electric water heater and an electric dryer. Because IMEF folds the dryer in, the figure includes dryer electricity and is not the washer's own consumption. The machine-only share is not published: DOE's database files only IMEF, and ENERGY STAR, which splits the machine out, lists this model under no matching rating. The source is DOE CCD, retrieved 2026-10-25. For the same missing rating, an installed price range is also not published. The figure for any other water heater or dryer type is not available.
Read the rest
The water figure of 8,820 gallons comes from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, of 6.5, multiplied by the capacity of 4.6 at DOE's test use. This site calculated it; the registry does not publish a yearly total. Read it as a yearly total under DOE's test conditions, not as a measurement of your own household. Its cost is not stated, because no free national source publishes local water and sewer rates, and this page does not estimate one. The steps behind both yearly figures are set out in how the yearly energy and water figures are calculated.
The class here is the 870 models registered as top-loading, standard size. Their median IMEF is 1.57, and this Whirlpool model, sold as WTW5020S**, is registered at 1.57. The two values are equal as published, so no difference can be read from the registry. Running cost depends on your own utility electricity tariff, which this text does not know, so the page computes it from your ZIP instead of stating an amount here. The 864 kWh figure is the quantity that calculation starts from. For other models in the same registry, see all clothes washer pages.
