Coming from a vented dryer, looked to invest in a heat pump one, that would hopefully be more future proof.
We knew getting one would require more time in running, they don't heat up to the temperature of a normal dryer.
Our last dryer took hour and a half, maybe 2 hours to dry fully, this heat pump one, I put on the maximum setting and longest dry time, and the clothes have always come out perfect, but it does take 4 hours 15 minutes.
For best results, do your wash load at night, put the dryer on delay, and run it through the night and make sure you stick anti crease on for a couple hours.
I don't split my loads up, everything is mixed, so if your someone who likes to separate clothes, then the dryer time would certainly be less.
