Model
Electrolux ELFW4222***
Rank #58 means 57 of the 388 washing machine models we track cost less to run each year; the 26th efficiency percentile means it uses less energy for its size than 26% of those models.
What does the Electrolux ELFW4222*** cost to run per year?
Do the math and the Electrolux ELFW4222***'s $17/yr puts it at rank #58 of 388, one of the more affordable washing machine models we track to keep running. Adjusted for size, it is only more efficient than 26% of washing machine models we track, so part of its running cost comes from its capacity rather than efficiency alone. Its IMEF of 2.13 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Whirlpool WFW92HEF** at $17/yr runs a little cheaper and the Lg WKHC152H*A at $17/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A washing machine typically stays in service for somewhere around 10 years; over that span, the Electrolux ELFW4222***'s $17/yr adds up to roughly $170 in electricity alone, before purchase price or repairs.
Also sold as: Lg WKHC152H*A.
By the numbers
The Electrolux ELFW4222*** normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $17/yr, here is what the Electrolux ELFW4222*** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Electrolux ELFW4222*** costs about $170. That is roughly $30 less than the class median, which would run closer to $200 over the same ten years.
How the Electrolux ELFW4222*** compares
The washing machine class we track runs from $7 to $58 a year. At $17/yr, it runs about $3 a year cheaper than the class median of $20, and it is about $10 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.4 cu ft, the Electrolux ELFW4222*** is a small washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, and smaller washing machine models generally cost less to run for the same job, all else being equal. Beyond size, its IMEF of 2.13, below the class median of 2.76, is the class's own efficiency yardstick, integrated modified energy factor, and it is what separates two similarly sized models with different running costs.
- Spin and wash efficiency (IMEF). A higher Integrated Modified Energy Factor means the machine wrings more useful washing (and a drier spin) out of every kilowatt-hour and gallon it uses.
- Drum volume. Drum volume sets the ceiling on how much a single cycle can wash, and it is usually the first driver of a washer's per-cycle energy use.
- Water heating. Cycle temperature, more than drum size, is usually what separates a cheap wash cycle from an expensive one on models with an internal water heater.
Common questions
Is the Electrolux ELFW4222*** cheap to run?
Yes, relatively. At $17 a year it ranks #58 of 388 washing machine models we track, in the cheaper part of its class to run.
How much does the Electrolux ELFW4222*** cost per month?
Roughly $1.39/mo, spreading the $17/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 90 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $17 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Electrolux ELFW4222*** for its size?
26th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
