Bosch Series 4 8kg Heat Pump Tumble Dryer

An 8 kg freestanding heat pump dryer with Auto Dry sensing, the Sensitive Drying System and an EasyClean filter designed to make routine maintenance straightforward.

The WTH85225IE is Bosch's Series 4 heat pump tumble dryer, a white freestanding machine rated for 8 kg loads in a standard 60 cm space. Heat pump drying recirculates warm air rather than venting it, so there is no hose to run outside and no window to leave open, which makes it workable in a flat or an internal utility room.

Auto Dry is the feature that earns its keep. Rather than running for a set time, the programme finishes when the load reaches the dryness level you selected, so cotton comes out ready to fold instead of over-dried. Alongside it, the Sensitive Drying System and a stainless steel drum handle fabrics gently, and a fine-tuning control lets you nudge the drying level up or down to taste.

Ideal for

Flats and apartments

Condenser drying means no external vent, so the machine can live in a hallway cupboard or an internal utility area. Water collects in a container, or you can plumb it to a drain.

Smaller households

An 8 kg rated capacity suits couples and small families, and Super Quick 40 is there for smaller loads when you need something back the same evening.

Tight utility rooms

At 84.2 by 59.8 cm it slides under a standard worktop, and an optional stacking kit puts it above a washing machine when floor space runs out.

Key features

8 kg rated capacity

Bosch's rated load for the eco programme at full capacity, taking about three and a half hours, or two hours ten minutes at half load.

Auto Dry sensing

The cycle ends when the laundry reaches the dryness level you picked, with fine-tuning available if you prefer things a little drier or slightly damp for ironing.

Sensitive Drying System

Mild warm air and a stainless steel drum are designed to dry without creasing, with an anti-crease cycle keeping the load moving after the programme ends.

EasyClean filter

Bosch's filter design is built for simple routine cleaning, and a blocked filter indicator tells you when it needs attention rather than leaving you guessing.

AntiVibration side walls

Reinforced side panels reduce movement and noise during the cycle, which is worth having when the dryer sits in a kitchen rather than a separate utility.

24 hour delay timer

Set the finish time up to a day ahead, so a load can be timed to end when you get home instead of sitting damp in the drum.

More to know

What heat pump drying changes

A heat pump dryer reuses the heat it has already generated instead of throwing it away, which is why it draws only 600 watts and finishes an eco cycle at 1.38 kWh. It also means no ducting: the moisture removed from your clothes is condensed and collected in a container you empty, or piped to a drain if you would rather not think about it. The trade-off is a longer cycle, at 3:25 for a full eco load.

Programmes for real laundry

Beyond cotton and easy care, the programme list covers woollens, mixed loads, towels, sportswear, shirts and blouses, and delicates, plus timed warm and timed cold options when you want to control the length yourself. Super Quick 40 is there for smaller loads. Low heat and reduced ironing are available as options, and a reload function lets you open the door mid-cycle to add the sock you found under the bed.

Energy label and running noise

On the current EU label the WTH85225IE sits at energy class E, using 1.38 kWh per eco cycle or 138 kWh per hundred cycles, with a condensation efficiency of 83 per cent in class C. Noise is quoted at 63 dB(A), noise class B, which is audible through a closed door but not intrusive, and the AntiVibration side walls are there to keep the cabinet steady. Bosch also gives it repairability class A, and the machine can be stacked above a washing machine with an optional kit.
