A large number of clothes dryers in Europe (save for the UK, which still uses a lot of hotboxes) are condensation dryers. Some countries (Sweden I believe) actually don't allow vented hotbox dryers for new construction due to building codes explicitly barring them. Heat pump dryers have been around for about 3-4 years now, but condensation dryers have been around for decades. In the US, but have been running Bosch condensation dryers for over a decade. Previous rental had one and the immediate difference I noticed was how much longer my clothes lasted from the cooler temps, so when I moved I bought my own W/D. No regrets.
