I agree with your thinking. I recommended Sterno (gelled alcohol) for a tent heater on the other thread because it is far safer than petroleum products. It burns cleaner, extinguishes easier, and obviously doesn't spill/splash as easily. It has the drawback of not cooking as well as liquid fuels, including liquid alcohol, but as a tent or food warmer it's hard to beat.

I personally would do without a heater in a tent unless facing hypothermia.
