Best capacity for a UK heat pump tumble dryer: 7kg, 8kg or 9kg?
Pick the right heat pump dryer drum size for UK households in 2026. When 7kg is enough, when 9kg is safer for bedding, and what to measure first.
Capacity is printed in kilograms of cotton. It is a lab figure, not a promise that every duvet will spin happily. For most UK homes in 2026, the useful shortlist is 8 kg or 9 kg.
Who can live with 7–8 kg
- One or two people
- Mostly clothing and towels
- Occasional single duvet covers, not king bedding every week
An 8 kg heat pump dryer is a strong everyday choice if bedding is rare.
When 9 kg is the safer buy
- Family laundry
- Regular double or king duvets
- Sports kit plus school uniforms in the same week
Oversizing slightly is usually better than running two half loads because you stuffed a duvet and the sensors got confused.
Measure more than the drum
Check depth with the door open, hose routing, and stacking height. A 9 kg machine that does not fit the cupboard is useless no matter how good the energy label looks.
Features that matter as much as kg
Self-cleaning condensers, gentle drum programmes, and low noise help more than chasing one extra kilogram. Use our compare view to scan capacity next to energy class and dB, then confirm dimensions on Amazon before you buy.
