> my laundry room has a vent and I’ve heard that heat pump tech still isn’t good enough

Heat pump dryers are in a slightly weird place in that they're boring old tech in Europe (they've been common for over a decade), and exciting new tech in the US. This means that dryers made for US preferences (physically larger, either three phase or <1500W, etc) are generally first or second models (and thus unreliable) while those made for European preferences are mature designs (and thus reliable).
