295 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 2.30 filed efficiency; the yearly figure is computed from it
A front-loading washer of standard size (1.6 cubic feet or more). Drum: 2.3 cubic feet.
If you are checking the Blomberg BLWM242300SWG, the figures here are 295 kWh a year with an electric water heater and electric dryer, and 2,510 gallons of water, both at DOE's test use. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.3, below the class median of 2.76.
Energy and water per year
295 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: 73 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.
2,510 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 295 kWh is this site's own calculation, not a registry entry. It combines the registry's IMEF of 2.3 with a capacity, the drum's volume in cubic feet, of 2.3, at DOE's test use for one year. The scope is an electric water heater and an electric dryer, so the dryer's energy is inside the total. The machine-only figure, as ENERGY STAR files it, is 73 kWh. That covers the washer and its electrically heated water, with the dryer not included. The IMEF and capacity come from the DOE certification database, retrieved 2026-10-25. The steps are set out in how the yearly energy and water figures are calculated.
Read the rest
The water figure of 2,510 gallons starts from the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, which is 3.7 for this model. The site multiplies it by the capacity of 2.3 and by DOE's test use for a year. It is a value at test conditions, not a measurement from any home, so a household with different loads or a different number of cycles will use a different amount. The cost of this water is not stated. No free national source publishes local water and sewer rates, and this page does not estimate one.
The 360 models registered as front-loading, standard size, have a median IMEF of 2.76. This model's IMEF of 2.3 is below that median, which means less laundry washed per kilowatt-hour at test conditions. The registry data here does not say why, and it does not describe how the machine performs in use. The running cost is not written in the text because it depends on your own electricity tariff. The page computes it from your ZIP. The installed price range sits in its own block with its source and date. Other models are listed on the clothes washer pages.
