Checking the Whirlpool TH25NAZ50(3B), a standard-size front-loading washer? At DOE's test use it takes 299 kWh of electricity a year with an electric water heater and an electric dryer, and 2,643 gallons of water. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.76, equal to its class median.


Energy and water per year

299 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: 80 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.

2,643 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 299 kWh figure assumes an electric water heater and an electric dryer, so it counts drying energy as well as washing. This site computed it, not the registry. It combines the model's IMEF of 2.76 with its capacity, the drum's volume in cubic feet, of 2.8, at DOE's test use. Both inputs come from the DOE Compliance Certification Database, retrieved 2026-10-25. ENERGY STAR files a separate machine-only figure of 80 kWh a year. That covers the machine and its electrically heated water alone, with the dryer left out. The rest of the 299 kWh total is the dryer's share under the test assumptions. Neither figure is available for a home with a gas water heater or a gas dryer. The steps behind both figures are set out in how the yearly energy and water figures are calculated. The model is sold as WFH5424S**.

Read the rest

At DOE's test use, this washer uses 2,643 gallons of water a year. This site derived that total from the model's IWF, the gallons of water used per cycle for each cubic foot of drum, of 3.2. It multiplied the IWF by the 2.8 cubic-foot capacity at the same test use. The registry publishes the IWF, not a yearly water total. The page states no cost for this water. No free national source publishes local water and sewer rates, so any cost figure would be an estimate. A reader who knows the local water and sewer rate can apply it to 2,643 gallons. The total reflects DOE's test use, not a household's own laundry pattern, which is not known here.

Among the 360 models registered as front-loading, standard size, this washer's IMEF of 2.76 is equal to the class median of 2.76. It holds the 101st highest IMEF of the 360. It is rated above the federal minimum IMEF for its class, where 37 models in the class sit. The running cost is not stated in this text, because it depends on the reader's own utility electricity tariff. The page computes it from the reader's ZIP instead, applied to the 299 kWh total. The installed price range appears in its own block with its source and date. It is a modeled installed-cost range, not a quote. Other models in the registry are listed on all clothes washer pages.
