449 kWh a year DOE CCD (opens in a new tab) (the U.S. Department of Energy’s Compliance Certification Database) · 2026-10-25with an electric water heater and an electric dryer
IMEF 1.84 filed efficiency; the yearly figure is computed from it
A front-loading washer of standard size (1.6 cubic feet or more). Drum: 2.8 cubic feet.
If you are checking the HISENSE WF5S2845BW, it uses 449 kWh of electricity a year at DOE's test use with an electric water heater and an electric dryer. It uses 3,882 gallons of water a year on the same basis. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 1.84, exactly its class's federal minimum.
Energy and water per year
449 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.
3,882 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. 323 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 front-loading washers. That is a class assumption, not this model’s rating or a warranty — no registry publishes either.

The 449 kWh figure covers more than the washer itself. This site computed it, not the registry. It uses the registry's IMEF and the model's capacity, the drum's volume in cubic feet, which is 2.8. The calculation assumes DOE's standard yearly number of test cycles, an electric water heater and an electric dryer. IMEF folds in the energy needed to dry each load, so part of the 449 kWh belongs to the dryer. A machine-only figure would separate the washer's own use from that dryer share. DOE's database does not publish one. ENERGY STAR lists no matching rating for this model, so the washer's own share is not available. The steps are set out in how the yearly energy and water figures are calculated. The registry data comes from DOE CCD, retrieved 2026-10-25.
Read the rest
The 3,882 gallons a year also comes from this site's calculation, not from the registry. It starts from the model's IWF, the gallons of water used per cycle for each cubic foot of drum, which is 4.7. That factor is applied to the 2.8 cubic-foot drum at DOE's standard yearly cycle count. A household that runs more or fewer loads than the test assumes will use a different amount. The page states no water cost for the 3,882 gallons. No free national source publishes local water and sewer rates, and the page does not estimate a cost. A reader who knows the local rate can apply it to the yearly gallons directly.
This model is compared with the 360 models registered as front-loading, standard size. Their median IMEF is 2.76. This model's IMEF of 1.84 sits below that median and exactly at the federal minimum for the class. The class holds 37 models at that minimum, so no rank is claimed inside the tie. Under the same test conditions, a lower IMEF means less laundry washed per kilowatt-hour than the median model. The page shows no installed price range. The cost database needs the washer's own yearly energy, and only ENERGY STAR files it, with no matching rating here. Running cost depends on your own electricity tariff, so the page computes it from your ZIP. Other models are listed on all clothes washer pages.
