Since the weather has got colder I have got one of those hangers with all the pegs on for socks and undies hung on the certain rails in all the bedrooms.
They dry quickly with the heat rising and keep the radiators for bigger stuff, I also have those airers for on the rads and find them very good too
Just remember if you do hang the driers from your rails to keep it behind your curtains when they are open or your neighbours might well be admiring your 'bunting' Lindaxx
