Checking the Maytag H18vB850(3B)? At DOE's test use, with an electric water heater and an electric dryer, it uses 481 kWh of electricity a year and 4,248 gallons of water. Its IMEF, the cubic feet of laundry washed per kilowatt-hour, dryer included, is 2.76. That equals the median of its front-loading, standard-size class.


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.

Service life: DOE’s cost database assumes 11 years for front-loading washers. That is a class assumption, not this model’s rating or a warranty — no registry publishes either.

What these figures mean

This site calculates the 481 kWh figure; the registry does not publish it. It 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 test use. That total assumes an electric water heater and an electric dryer, so it includes the energy to dry each load. ENERGY STAR files a separate figure of 128 kWh a year for this washer. That value covers only the machine and its electrically heated water, without the dryer. Only the 481 kWh figure includes the dryer, which is why the two figures differ. The method is set out in how the yearly energy and water figures are calculated. The registry values come from DOE CCD and were retrieved on 2026-10-25.

Read the rest

This site also calculates the 4,248 gallons a year, using the registry's figures. The calculation uses the IWF, the gallons of water used per cycle for each cubic foot of drum. This model's IWF is 3.2, applied to its 4.5 cubic-foot drum at the same test use. The figure reflects DOE's test use, not the reader's own household pattern. Its cost is not stated here. No free national source publishes local water and sewer rates, so the cost of 4,248 gallons depends on the reader's own water utility. Electricity works the same way. The running cost for the 481 kWh is not given in this text because it depends on the reader's own utility tariff. Instead, the page calculates it from the reader's ZIP.

The class used for comparison is the 360 models registered as front-loading washers of standard size. This model's IMEF of 2.76 is equal to the class median of 2.76. Ranked by IMEF, it is 101st highest of 360. It is rated above the federal minimum IMEF for its class, and 37 models in the class are rated at that minimum. The minimum value itself is not given in this data. The registry lists the model as sold under MHW5630H**. An installed-cost range appears in its own block on this page, with its source and date. That range is modeled, not a quote. Other models in the class can be checked from the index of all clothes washer pages.
