I remember my house always looking like a chinese laundry in winter when i had a child in cloth nappies... but mainly used flats.... they dried so much faster. But with my youngest I had a few MCNs and I hung them on a drier over our ducts (ours were on the floor so could get the heat nice and close). I also often put them in a hot oven! If I had just taken out a roast etc i would quickly gather up some nappies, pop them in a clean tray and use the remaining heat. The oven is cheaper than a tumble drier because it doesn't have a turning mechanism and fan to run as well as the heating element. Obviously be careful not to scorch by touching the oven's heating element.

My MIL had a fantastic set up! Her kitchen had an old fashioned combustion stove (similar to an Aga) which had a special plate warming area underneath... it was quite large.... about the size of two huggies boxes side by side... with shelves. She had put 5 babies' nappies through that drying system and always said she wondered how modern mothers coped without one!
