Checking the Maytag H18vB859(3B)? At DOE's test use, it takes 481 kWh of electricity a year with an electric water heater and an electric dryer, 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 2.76 median of front-loading, standard-size washers.
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: 128 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.

This site calculates the 481 kWh figure; the registry does not publish it. The figure combines the registry's IMEF of 2.76 with the model's capacity, the drum's volume in cubic feet, of 4.5, at DOE's yearly test use. IMEF counts the dryer, so this total covers the washer, its electrically heated water and the electric dryer. ENERGY STAR files a separate figure of 128 kWh a year for the machine and its electrically heated water alone. The gap between 128 kWh and 481 kWh reflects the dryer: the larger figure includes it, and the smaller one does not. This page has no figure for a home with a gas water heater or a gas dryer. The method behind the yearly energy and water figures sets out each step of the calculation.
Read the rest
This site also calculates the 4,248 gallons a year. It multiplies the registry's IWF, the gallons of water used per cycle for each cubic foot of drum, of 3.2 by the 4.5 cubic-foot capacity at DOE's test use. A household that runs more or fewer loads than the test assumes will use a different amount. No figure for that case is available here. The page does not state what this water costs. No free national source publishes local water and sewer rates, so any cost figure here would be an estimate. A reader who knows the local water and sewer rate can apply it to the 4,248 gallons figure.
This model's IMEF of 2.76 ranks 101st highest among the 360 models registered as front-loading, standard size. That value equals the class median of 2.76. It is also rated above the federal minimum IMEF for the class, and 37 models in the class sit at that minimum. The registry entry lists the model as sold under MHW5630H**, MHW5630M**. The yearly running cost is not written here because it depends on the reader's own electricity tariff. The page computes that cost from the reader's ZIP. The installed-cost range appears in its own block with its source and date. It is a modeled range, not a quote. Other models in this class are on the clothes washer pages.
