Model
Electrolux ELFW7337***
Rank #12 means 11 of the 388 washing machine models we track cost less to run each year; the 100th efficiency percentile means it uses less energy for its size than 100% of those models.
What does the Electrolux ELFW7337*** cost to run per year?
At $9 a year to run, the Electrolux ELFW7337*** is one of the very cheapest washing machine models we track, ranking #12 of 388, in the bottom five percent on cost. Efficiency-wise, once its capacity is accounted for, it edges out 100% of the class, about as strong a result as this ranking produces. At a IMEF of 2.76, its integrated modified energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Truarctic TWF3124HSW at $7/yr runs a little cheaper and the Electrolux ELTE7300*** - at $9/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 ELFW7337***'s $9/yr adds up to roughly $90 in electricity alone, before purchase price or repairs.
Also sold as: Electrolux ELTE7300*** -, Electrolux ELTE730C*** -, Electrolux ELTG7300*** -, Frigidaire FWFX22D4EW.
By the numbers
The Electrolux ELFW7337*** 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 $9/yr, here is what the Electrolux ELFW7337*** 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 ELFW7337*** costs about $90. That is roughly $110 less than the class median, which would run closer to $200 over the same ten years.
How the Electrolux ELFW7337*** compares
The washing machine class we track runs from $7 to $58 a year. At $9/yr, it runs about $11 a year cheaper than the class median of $20, and it is about $2 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.4 cu ft, the Electrolux ELFW7337*** is a small washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. The IMEF of 2.76 on this model, above the class median of 2.76, measures integrated modified energy factor; it is the number to compare directly against another model's IMEF if capacity is similar.
- 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 ELFW7337*** cheap to run?
Yes, relatively. At $9 a year it ranks #12 of 388 washing machine models we track, in the cheaper part of its class to run.
How much does the Electrolux ELFW7337*** cost per month?
Roughly $0.77/mo, spreading the $9/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 50 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $9 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Electrolux ELFW7337*** for its size?
100th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
