If you are checking Whirlpool V21zAe56(3B) against the registry, DOE's test use with an electric water heater and electric dryer gives 745 kWh and 6,596 gallons a year. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.06, above the class median of 1.57.
Energy and water per year
745 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: 260 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.
6,596 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.

The figure of 745 kWh includes the washer, its electrically heated water and an electric dryer. This site computed it, not the registry, from the registry's IMEF of 2.06 and a capacity, the drum's volume in cubic feet, of 5.2 cubic feet, at DOE's test use. The source is DOE CCD, retrieved 2026-10-25. ENERGY STAR separately files 260 kWh for the machine and its electrically heated water alone, with the dryer not included. The two figures come from different sources, so their gap is only an approximate indication of the dryer's share. The steps are described in how the yearly energy and water figures are calculated.
The water figure is 6,596 gallons. This site computed it from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, of 4.3 and the same capacity of 5.2 cubic feet, at DOE's test use. Its cost is not stated: no free national source publishes local water and sewer rates, so any amount would be an estimate. The running cost is also not given in the text, because it depends on your own utility electricity tariff. The page computes it from your ZIP code, using the electricity use of 745 kWh under the conditions stated above.
