I keep my snakes in my room which is probably the warmest room in the house. The ambient room temperatures were great for the cool side during the summer, but now that it's cooling down it isn't working (cool side is getting down to 77).

I've looked into buying a space heater to keep the room temps up to 80-82. When I suggested this to my mother, she was horrified. She said they're incredibly dangerous, and I'd burn the house down. Are they really this dangerous? What safety precautions should I take? Also, are there any specific heaters you'd recommend?

Thank you for any information!
