What drives the difference
- Heat pump dryer: Heat pump dryers recycle heat in a closed loop and draw 500-1,500 W, using about 1-1.5 kWh per load, roughly half of a conventional electric dryer. Cycles take longer.
- Compact dryer: Compact and ventless condenser dryers dry smaller loads with 1,300-3,600 W elements over longer cycles, using about 1.5-2.5 kWh per load.
Ways to cut either cost
Air-drying delicates and towels saves the remaining kWh.
