Thanks, that obviously makes more sense. (I think I was thinking about heat pump clothes dryers at the same time I was making that comment.)

  Heat pump dryers don’t cool the room either because they work in a closed loop. There’s no external vent removing hot air to the outside like a conventional dryer. So they pull heat from the room but also put it back in the room, and the overall effect is to warm up the room slightly.
