Model
Speed Queen ADEE9***178T***
Rank #363 means 362 of the 615 clothes dryer models we track cost less to run each year; the 27th efficiency percentile means it uses less energy for its size than 27% of those models.
What does the Speed Queen ADEE9***178T*** cost to run per year?
At $113 a year to run, the Speed Queen ADEE9***178T*** sits close to the middle of its class on cost, ranking #363 of 615 clothes dryer models we track. Once capacity is factored in, its efficiency percentile of 27 is below the class median, worth weighing alongside the raw dollar figure. The CEF figure of 3.93 on this model captures combined energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Speed Queen ADE6H***178T*** at $113/yr runs a little cheaper and the Samsung DVE54CG7155* at $113/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 Speed Queen ADEE9***178T***'s $113/yr adds up to roughly $1469 in electricity alone, before purchase price or repairs.

What drives its running cost
At 6.9 cu ft, the Speed Queen ADEE9***178T*** 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, 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. The CEF of 3.93 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.
