257 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 1.49 filed efficiency; the yearly figure is computed from it
A compact top-loading washer (under 1.6 cubic feet). Drum: 1.3 cubic feet.
If you are checking the COSTWAY FP11187US-GR: at DOE's test use, with an electric water heater and an electric dryer, it uses 257 kWh a year and 4,142 gallons of water. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 1.49, above the class median of 1.25.
Energy and water per year
257 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.
4,142 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.

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 257 kWh figure covers the washer, an electric water heater and an electric dryer together. The DOE CCD, the registry this data comes from, files IMEF rather than the washer's own use, and IMEF folds the dryer in. This site computed the yearly figure from the registry's IMEF of 1.49 and a capacity, the drum's volume in cubic feet, of 1.3, at DOE's fixed yearly test use. The registry does not publish the yearly figure itself, and the DOE CCD data was retrieved 2026-10-25. A machine-only figure is not available for the COSTWAY FP11187US-GR: only ENERGY STAR splits the washer out, and it lists this model under no matching rating. The calculation is set out in how the yearly energy and water figures are calculated.
Read the rest
The water figure of 4,142 gallons comes from IWF, the gallons of water used per cycle for each cubic foot of drum, which is 10.8 for this model. This site combined it with the capacity of 1.3 and the same yearly test use. The result describes DOE's test conditions, not your household's own cycle count. The cost of that water is not stated: no free national source publishes local water and sewer rates, and this page does not estimate an amount. The same limit applies to electricity. The running cost of the 257 kWh depends on your own utility tariff, so the page computes it from your ZIP instead of printing a figure in the text.
The comparison group is the 48 models registered as top-loading, compact. Their median IMEF is 1.25, and the 1.49 of this model is above it. A higher IMEF means more laundry washed per kilowatt-hour with the dryer included. The registry data used here does not show how much that difference changes a given household's use. The installed price range is not published: the cost database needs the washer's own yearly energy, which only ENERGY STAR files, and it lists no matching rating for this model. Other models in this class are listed on the clothes washer pages.
