Model
Smeg WM24UWH
Rank #164 means 163 of the 388 washing machine models we track cost less to run each year; the 14th efficiency percentile means it uses less energy for its size than 14% of those models.
What does the Smeg WM24UWH cost to run per year?
Among the 388 washing machine models we track, the Smeg WM24UWH's $20/yr running cost ranks it #164, close to dead center. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 14% of the models we track. The IMEF figure of 2.1 on this model captures integrated modified energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Blomberg WM98220SX* at $20/yr runs a little cheaper and the Haier QFW150S*N*** at $20/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 Smeg WM24UWH's $20/yr adds up to roughly $200 in electricity alone, before purchase price or repairs.
Also sold as: Beko WFTV10733XC*.
By the numbers
The Smeg WM24UWH 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 $20/yr, here is what the Smeg WM24UWH adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Smeg WM24UWH costs about $200. That is roughly $0 less than the class median, which would run closer to $200 over the same ten years.
How the Smeg WM24UWH compares
The washing machine class we track runs from $7 to $58 a year. At $20/yr, it sits right on the class median of $20, and it is about $13 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.3 cu ft, the Smeg WM24UWH 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 2.1, 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 Smeg WM24UWH cheap to run?
Roughly, yes. Its $20/yr figure is close to the class median, ranking #164 of 388, neither a bargain nor a splurge on running cost.
How much does the Smeg WM24UWH cost per month?
About $1.64 a month, which is the $20 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: 106 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $20 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Smeg WM24UWH for its size?
14th percentile once size is factored in, a fairly typical result for the class.
