I am not a hedgie owner, but I use a space heater for for my spider room. If you choose to go with a space heater, I also recommend one has a thermostat, it will turn on when temperatures go below your desired setting. I use a bionaire tower. It has a safety that will automatically shut the heater off when it is knocked over, or even just slightly tipped, which I think is great. My space heater is plugged in 24/7 during the winter, and I've had no problems.
