I am very short on space and can’t fit a tumble dryer in the kitchen. I had a condenser dryer under the stairs for a bit but it caused damp on the wall behind it despite emptying the water thing in it. It’s impossible for us to carry a full size vented tumble dryer upstairs so i wondered if anyone had bought and used one of the small 3.5 kilo vented tumble dryers in a box room upstairs. I was going to put the vent hose out of a window. Can anyone give me any advice or recommendations please ?
