I'm moving house soon and have two small children so I want to buy a vented tumble dryer at last. At the moment I have a washer dryer which I've stopped using because it never gets the clothes dry. The only space in the kitchen is opposite the external wall. Would I be able to keep the dryer there but move it across the kitchen when I want to use it so I can put the tube out of the window? It's a bit of a silly question but I've never had a separate dryer before and have no idea how easy or not it would be to move the dryer.
