Not sure what is so different in my user case to all the others above, but we have a Bosch Heat Pump one, and it it brilliant.
It lives in the utility room with boiler and washing machine. The condensate is plumbed in.
Unless it is summer, or a guaranteed dry day, absolutely everything goes on the ‘mixed load’ setting.
1hr28 minutes and it is dry. Whether that be 5 large towels, full sets of bedding, mixed adult/child clothes or sports kit.
There are about 20 different programmes for different load types, plus bizarrely WiFi connectivity and an app, but we just ignore this and use the mixed load setting.
