Model
Miele WXC280
Rank #209 means 208 of the 388 washing machine models we track cost less to run each year; the 5th efficiency percentile means it uses less energy for its size than 5% of those models.
What does the Miele WXC280 cost to run per year?
The Miele WXC280 holds rank #209 of 388 on running cost, at about $22 a year, an unremarkable but typical figure for the class. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 5% of the models we track. At a IMEF of 2.24, 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 Miele WWD660 at $22/yr runs a little cheaper and the Miele WXD160 at $22/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 Miele WXC280's $22/yr adds up to roughly $220 in electricity alone, before purchase price or repairs.
Also sold as: Miele WWD160.
By the numbers
The Miele WXC280 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 $22/yr, here is what the Miele WXC280 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Miele WXC280 costs about $220. That is roughly $20 more than the class median, which would run closer to $200 over the same ten years.
How the Miele WXC280 compares
The washing machine class we track runs from $7 to $58 a year. At $22/yr, it runs about $2 a year above the class median of $20, and it is about $15 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.3 cu ft, the Miele WXC280 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. Its IMEF of 2.24, below the class median of 2.76, reflects integrated modified energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- Spin and wash efficiency (IMEF). IMEF is this class's core efficiency yardstick; two washers with the same drum size can carry meaningfully different IMEF figures and running costs.
- Drum volume. A larger-capacity washer can wash more per load, which can lower cost per pound of laundry, but it also draws more water and energy per cycle if you are not filling it.
- Water heating. Most washers rely on your home's hot water supply, but internal-heater sanitize or hot-wash cycles use meaningfully more electricity than a cold or warm wash.
Common questions
Is the Miele WXC280 cheap to run?
Roughly, yes. Its $22/yr figure is close to the class median, ranking #209 of 388, neither a bargain nor a splurge on running cost.
How much does the Miele WXC280 cost per month?
About $1.79 a month, which is the $22 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 116 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $22 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Miele WXC280 for its size?
5th percentile once size is factored in, a fairly typical result for the class.
