Bosch Series 6 WQH246DRGB 9kg Heat Pump Tumble Dryer - Graphite vs Series 4 8kg Heat Pump Tumble Dryer - White — Comparison

The Bosch Series 6 WQH246DRGB 9kg Heat Pump Tumble Dryer - Graphite at £849 and the Bosch WTH85225GB Series 4 8kg Heat Pump Tumble Dryer - White at £629 sit in Bosch's tumble dryer line-up with different priorities. WQH246DRGB is the higher-series, larger-capacity graphite model with more premium care features, while WTH85225GB is the Series 4 8kg heat pump dryer, positioned as the more affordable Bosch option.

On the supplied specs, WQH246DRGB lists Hygiene Plus, SelfCleaning Condenser, Speed Perfect, A++ energy rating and 64 noise level. WTH85225GB has heat pump design, 8kg capacity, Auto Dry, Anti-Vibration Design, LED display, Anti Crease, A++ energy rating and a 65dB noise rating. Both are A++ heat pump dryers, but the Series 6 adds 9kg capacity, SelfCleaning Condenser, Hygiene Plus and Speed Perfect, while Series 4 counters with Auto Dry, LED display and Anti Crease. The practical effect is the Series 6 is about capacity and convenience, while Series 4 covers the essentials at a lower price, so the dearer model only makes sense when that advantage will be used regularly.

WQH246DRGB suits families wanting a 9kg drum, hygiene-focused drying and reduced condenser maintenance in a darker finish. WTH85225GB suits buyers who can live with 8kg capacity and want Bosch heat pump drying, Auto Dry and anti-vibration design without paying Series 6 money. The price gap is £220, so the larger drum and SelfCleaning Condenser need to be valued, which matters when you are balancing upfront cost against weekly laundry volume, energy priorities and available space. For best value, choose the model whose extra feature you will use often, not simply the one with the longer specification list.

Bottom line: "choose WQH246DRGB if you want 9kg capacity, Hygiene Plus, Speed Perfect and SelfCleaning Condenser in graphite / opt for WTH85225GB if an 8kg Series 4 heat pump dryer at £629 is the better-value Bosch choice."
