Bosch Series 6 WQG24502GB (9kg heat pump, self-cleaning condenser)

The Series 6 is the pragmatic pick for most energy-conscious homes. It pairs an Auto Dry moisture sensor with a self-cleaning condenser that automatically clears lint off the heat exchanger — a genuine efficiency edge, because a clogged condenser quietly raises running cost and time. As with any heat-pump dryer you still empty the door fluff filter after cycles (Bosch's manual asks you to clean it regularly), but the condenser itself needs no manual upkeep. At 193 kWh/year its energy use is near-identical to the pricier AEG, and at 61 dB it's the quietest on this list, which matters if you run cycles overnight to catch a cheap off-peak tariff. Bosch's current promotional 5-year parts-and-labour warranty (register the qualifying purchase within three months to activate the full term) and independent round-ups naming it a best-overall-value heat-pump dryer back up the value case. The trade-off against the AEG is top-of-test delicate care; against the budget pair below, you pay more but gain the self-cleaning condenser and a longer warranty. (The WQG245A0GB is the same machine in a different finish.)
