In context of the above, you maybe interested to hear that my latest Ebac has come with a specific function button setting for "clothes drying".
Normally it runs in "Smart mode" which works well.
Drying mode speeds the fan up, and perhaps alters the relative humidity setting? It then allows you too choose a 2 or 4 hour drying cycle!
Am trying to experiment a bit to see if this is better than the tumble drier, by better I mean cheaper, and warmer indoors, by blowing dry warm air into the house, as opposed to warm wet air to outdoors...
