Model
Bosch WTW87NH1UC
Rank #2 means 1 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 WTW87NH1UC cost to run per year?
The Bosch WTW87NH1UC costs about $23 a year to run, a figure that only a handful of the 615 clothes dryer models we track can beat, rank #2. Efficiency-wise, once its capacity is accounted for, it edges out 100% of the class, about as strong a result as this ranking produces. The CEF figure of 6.8 on this model captures combined energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Bosch WQB245AXUC at $23/yr runs a little cheaper and the Samsung DV25B69**H* at $23/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A clothes dryer typically stays in service for somewhere around 13 years; over that span, the Bosch WTW87NH1UC's $23/yr adds up to roughly $299 in electricity alone, before purchase price or repairs. At rank #2 of 615, it is one of the single cheapest clothes dryer models we track to run, in the top one percent on cost.
Also sold as: Samsung DV25B69**H*, Samsung DV25FG50*0**.
By the numbers
The Bosch WTW87NH1UC 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 WTW87NH1UC 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 WTW87NH1UC 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 WTW87NH1UC 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 4 cu ft, the Bosch WTW87NH1UC 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 6.8, 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 WTW87NH1UC cheap to run?
Yes, relatively. At $23 a year it ranks #2 of 615 clothes dryer models we track, in the cheaper part of its class to run.
How much does the Bosch WTW87NH1UC cost per month?
Roughly $1.93/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 125 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 WTW87NH1UC 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.
