Model
Blomberg BLWM242300SWG
Rank #23 means 22 of the 388 washing machine models we track cost less to run each year; the 37th efficiency percentile means it uses less energy for its size than 37% of those models.
What does the Blomberg BLWM242300SWG cost to run per year?
The Blomberg BLWM242300SWG holds rank #23 of 388 on running cost, at about $14 a year, a genuinely cheap result for the class. Efficiency-wise, once size is accounted for, it trails most of the class, ahead of only 37% of the models we track. Its IMEF of 2.3 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Beko BWM242300SWW at $14/yr runs a little cheaper and the Electrolux ELFW7738*** at $14/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 Blomberg BLWM242300SWG's $14/yr adds up to roughly $140 in electricity alone, before purchase price or repairs.
Also sold as: Beko BWM242300SWW.
By the numbers
The Blomberg BLWM242300SWG 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 $14/yr, here is what the Blomberg BLWM242300SWG adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Blomberg BLWM242300SWG costs about $140. That is roughly $60 less than the class median, which would run closer to $200 over the same ten years.
How the Blomberg BLWM242300SWG compares
The washing machine class we track runs from $7 to $58 a year. At $14/yr, it runs about $6 a year cheaper than the class median of $20, and it is about $7 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.3 cu ft, the Blomberg BLWM242300SWG is a small washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Its IMEF of 2.3, 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 Blomberg BLWM242300SWG cheap to run?
Yes. Its $14/yr running cost puts it at rank #23 of 388, below what most washing machine models we track cost to run.
How much does the Blomberg BLWM242300SWG cost per month?
About $1.13 a month, which is the $14 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: 73 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $14 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Blomberg BLWM242300SWG for its size?
37th 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.
