If you are verifying the Maytag H18vB944(3B), here are its yearly figures at DOE's test use. With an electric water heater and an electric dryer, this front-loading washer uses 513 kWh a year and 4,531 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
513 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: 143 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.
4,531 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 513 kWh figure is computed by this site, not published by the registry, from DOE Compliance Certification Database data retrieved 2026-10-25. It combines the registry's IMEF of 2.76 with the model's capacity, the drum's volume in cubic feet, which is 4.8. That total covers running the washer, heating its water electrically and drying each load in an electric dryer. ENERGY STAR files a machine-only figure of 143 kWh a year, which counts the washer and its electrically heated water but not the dryer. The gap between 143 kWh and 513 kWh therefore reflects the dryer's share at DOE's test use. The method behind the yearly energy and water figures sets out how this calculation is done.
Read the rest
The 4,531 gallons a year comes from the model's IWF, the gallons of water used per cycle for each cubic foot of drum, which is 3.2. This site multiplies that factor by the 4.8 cubic feet of capacity at DOE's test use, because the registry lists no yearly gallons. The result reflects DOE's test use, not a count of any household's actual loads. No cost is shown for this water because no free national source publishes local water and sewer rates. A reader checking a water bill would need the local utility's rate to put a price on 4,531 gallons.
Among the 360 models registered as front-loading, standard size, this washer's IMEF of 2.76 ranks 101st highest. That value is equal to the class median of 2.76, so the model sits at the middle of its class on this measure. It is rated above the federal minimum IMEF for its class, where 37 of the 360 models sit. The registry also lists this model as sold as MHW6630H**. Running cost is not given in this text, because it depends on your own electricity tariff; the page computes it from your ZIP. An installed-cost range appears in its own block with its source and date, as a modeled range rather than a quote. To check another model, see all clothes washer pages.
