Miele's heat pump dryers once defined longevity, T1 owners routinely saw 15 years of quiet, 120V plug-and-play service, but the warranty collapse from ten years to two tells you everything about where the engineering went. Recent buyers report F47 and F99 error codes within months, and Miele support has turned glacial when owners need help. The three-hour cycle is heat pump physics, not a flaw, but you're paying £1200, 2500 for a machine the manufacturer itself only trusts for 24 months. Hunt down a used T1 if you find one; otherwise, Bosch delivers five-year coverage at half the cost.
This is the dryer equivalent of a cast-iron skillet: unglamorous, built around a mechanical core that's been working since before the internet, and likely to outlast fancier alternatives. Cycles take longer than premium models and you get no heat pump efficiency or specialty modes, but the simplicity cuts both ways, fewer electronics mean fewer expensive board failures, and when something does wear out (usually a belt or door gasket after a decade), parts cost under $50 and most owners can swap them in an afternoon. Buy it if you value a 10+ year lifespan and hate service calls; skip it if you're chasing speed or energy savings.
