We run a heated bed on a RepRap, and even then we'll sometimes get warping on large parts. We're thinking a raft setting also helps, but I don't know if we've tried that yet. Not having run on unheated, I don't know how big of a difference it makes... but I do know that having some insulation on the bottom of the heating unit helps speed up turnaround time and gives a more even heating.
