I've been rolling the dice with one heater in my tanks for years on end and have never had any problems. Then again I'm never really away from my tank for any length of time though either. (aside from work) I think I'm more concerned about getting into a horrible car accident on my way to the LFS then I am about frying my tank. Earthquakes are something to worry about too where I'm located at. It's been about 28 years since the Loma Prieta quake hit so were about due. A faulty heater is pretty far down the list.
