Small laundry closet? Condo or ADU with no vent? The Bosch 800 Series 24″ Heat Pump Dryer (model WQB245AXUC) promises full-size results without ducting, gentle fabric care, and real energy savings—exactly what tight spaces and busy schedules need.

Quick take (why it’s worth it)

• Ventless heat-pump tech = install almost anywhere (no exterior vent required) while using less energy than traditional electric dryers.

• Compact 24″ footprint, 4.0 cu. ft. drum—fits apartments/closets, yet handles everyday loads.

• Fabric-friendly features: Steam Restore to reduce wrinkles + Self-Cleaning Condenser™ to keep performance high with low maintenance.

• Smart controls: Wi-Fi/Home Connect for remote monitoring and notifications.

What makes this dryer different?

1) Ventless heat-pump drying = flexible install + efficiency

Heat-pump systems recirculate warm air to extract moisture, so you don’t need a duct. That’s a huge win for condos, interior closets, or rentals where venting isn’t feasible—and it’s designed to be highly efficient.

2) Surprisingly capable capacity for 24″

At 4.0 cu. ft., this compact still handles towels, bedding, and typical weekly loads. If you’ve been living with a portable dryer, this is a major step up.

3) Fabric care extras you’ll actually use

• Steam Restore helps relax wrinkles and refresh garments you don’t want to rewash.

• Self-Cleaning Condenser™ automatically rinses lint off the condenser—less fuss, consistent performance.

4) App control & alerts

With Home Connect, start/stop cycles, get “cycle complete” pings, and see time remaining from your phone—handy when the laundry closet isn’t in your unit.

5) Built for stackability & tight spaces

It’s designed to stack with the matching Bosch 800 Series washer using a compatible stacking kit, and its compact dimensions make it closet-friendly. Noise is rated around 62 dBA—respectfully quiet for apartment living.

Power note: This model is 240V, not 120V. Plan your outlet accordingly.
