Checking the Electrolux ELFW7637***? With an electric water heater and an electric dryer, DOE's test use gives 481 kWh a year and 4,248 gallons of water. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.76, equal to the class median of 2.76.
Energy and water per year
481 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: 85 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.
4,248 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 yearly energy figure of 481 kWh comes from this site, not from the registry. It uses the registry's IMEF of 2.76 and the capacity, the drum's volume in cubic feet, listed as 4.5, at DOE's test use of a fixed number of cycles a year. It assumes an electric water heater and an electric dryer. The source is the DOE Compliance Certification Database, retrieved 2026-10-25. ENERGY STAR files a separate machine-only figure of 85 kWh. That covers the machine and its electrically heated water alone, with the dryer not included. The dryer's own share is not available as a separate value on this page.
The yearly water figure of 4,248 gallons is also calculated by this site. It combines IWF, the gallons of water used per cycle for each cubic foot of drum, listed as 3.2, with the capacity of 4.5, at DOE's test use. A household that washes more or fewer loads than DOE's test use will see a different total. The water cost is not stated. No free national source publishes local water and sewer rates, and this page does not estimate a price. The calculation method sets out each step behind the energy and water figures.

This model's IMEF of 2.76 equals the class median of 2.76. The class is the 360 models registered as front-loading, standard size. The registry lists more than one rating for this model, sold as ELFW7437***, ELFW7537***, ELFW7626***, and the page shows the least efficient one. The running cost is not stated in the text. It depends on your own utility electricity tariff, so the page computes it from your ZIP code. A modeled installed-cost range appears in its own block with its source and date.
