What does the Miele TWI180 WP cost to run per year?
Almost nothing we track in this class costs less to run than the Miele TWI180 WP: about $25 a year, rank #13 of 615. Adjusted for its cef, it is more efficient than 98% of clothes dryer models we track, one of the strongest results in the whole class. At a CEF of 6.37, its combined energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Miele TWF160 WP at $25/yr runs a little cheaper and the Miele TWB120 WP at $25/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 Miele TWI180 WP's $25/yr adds up to roughly $325 in electricity alone, before purchase price or repairs.

What drives its running cost
At 4.1 cu ft, the Miele TWI180 WP 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, and smaller clothes dryer models generally cost less to run for the same job, all else being equal. The CEF of 6.37 on this model, above the class median of 3.93, measures combined energy factor; it is the number to compare directly against another model's CEF if capacity is similar.
- 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.
