Every Bosch tumble dryer on this page is a freestanding heat pump condenser model from the Series 4, Series 6 or Series 8 lines. They suit households that want to dry indoors without fitting a vent hose and that care about running costs as much as the price. The same dryers also appear under Bosch freestanding tumble dryers and Bosch heat pump tumble dryers.

A heat pump dryer passes warm air through a heat exchanger and reuses it, so it dries at lower temperatures than a standard condenser dryer. That is kinder to fabrics and uses much less electricity. The trade-offs are longer cycles and a higher purchase price. Moisture is collected as water instead of being vented, so the dryer doesn't need to sit next to a window or an outside wall.

Capacity and energy rating set the ranges apart. Series 4 dryers take 8 kg loads and are rated A++. Series 6 and Series 8 dryers hold 9 kg and are rated A+++. Series 6 comes in white or graphite and offers 14 drying programmes. Some Series 6 models and the Series 8 dryers connect to the internet, so you can keep an eye on a cycle from your phone.

Start with load size. 8 kg covers most couples and smaller families, while 9 kg makes it easier to dry duvets and large weekly washes. Then decide whether app connectivity or a graphite finish is worth having. If you don't have room for two machines, compare Bosch washer dryers instead.
