Model
Bosch WQB245AXUC
Rank #1 means 0 of the 615 clothes dryer 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 Bosch WQB245AXUC cost to run per year?
At $23 a year to run, the Bosch WQB245AXUC is one of the very cheapest clothes dryer models we track, ranking #1 of 615, in the bottom five percent on cost. Once capacity is factored in, it outperforms 100% of the clothes dryer models we track on efficiency, near the very top of the normalized ranking. Its CEF of 6.97 reflects combined energy factor, one of the class's core efficiency levers.
On the leaderboard, the Bosch WTW87NH1UC at $23/yr runs a little more, the closest neighbor to its exact spot in the ranking. A clothes dryer typically stays in service for somewhere around 13 years; over that span, the Bosch WQB245AXUC's $23/yr adds up to roughly $299 in electricity alone, before purchase price or repairs. At rank #1 of 615, it is one of the single cheapest clothes dryer models we track to run, in the top one percent on cost.
By the numbers
The Bosch WQB245AXUC 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 $23/yr, here is what the Bosch WQB245AXUC adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Bosch WQB245AXUC costs about $230. That is roughly $900 less than the class median, which would run closer to $1130 over the same ten years.
How the Bosch WQB245AXUC compares
The clothes dryer class we track runs from $23 to $128 a year. At $23/yr, it runs about $90 a year cheaper than the class median of $113, and it is the cheapest clothes dryer to run in the class among the models we track.
What drives its running cost
At 3.9 cu ft, the Bosch WQB245AXUC is a small clothes dryer for its class, which spans 3.8 to 9.2 cu ft with a median of 7.4 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 CEF of 6.97, above the class median of 3.93, reflects combined 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.
- Heat source and Combined Energy Factor (CEF). CEF combines drying performance with standby and off-mode energy use; for a given drum size, a higher CEF means less energy per pound of laundry dried, and heat-pump models usually post the highest figures in the class.
- Drum capacity. Drum capacity sets how much laundry one cycle can hold, and heating a bigger volume of air generally costs more energy per cycle.
Common questions
Is the Bosch WQB245AXUC cheap to run?
Yes, relatively. At $23 a year it ranks #1 of 615 clothes dryer models we track, in the cheaper part of its class to run.
How much does the Bosch WQB245AXUC cost per month?
Roughly $1.89/mo, spreading the $23/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 122 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $23 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Bosch WQB245AXUC 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.
Cheaper to run in the same class
This is already the cheapest model to run in its class among the ones we track.
