Much less heat lost into the room.
5/5
I wanted a dryer that produced less eternal heat and condensation in my enclosed utility room and this is just the job!
Having the option of plumbing it into the waste water is a bonus, though the door mounted water collector is easy to empty and being visible, reminds everyone to do so, so we're using that for now.
It takes a longer to dry clothes than my old vented dryer, but they come out lovely and soft, with far fewer creases.
The super energy efficiency is a bonus which will soon pay for the investment. All round, I'm very pleased.
