Model
Speed Queen ADE6H***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 ADE6H***178T*** cost to run per year?
Ranking #363 of 615, the Speed Queen ADE6H***178T*** runs at roughly $113 a year, neither the cheapest nor the priciest in its class. Normalized for capacity, it beats only 27% of clothes dryer models we track, a below-average efficiency result. Its CEF of 3.93 reflects combined energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Samsung DVE55CG7105* at $113/yr runs a little cheaper and the Speed Queen ADEE9***178T*** 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 ADE6H***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 ADE6H***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, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Beyond size, its CEF of 3.93, above the class median of 3.93, is the class's own efficiency yardstick, combined energy factor, and it is what separates two similarly sized models with different running costs.
- 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.
