For Jon's inquiry about what feature of electric ceramic heaters makes them good, it's the lack of fumes (from petrochemical fuels) or red hot exposed electircal wires that can start fires. They seem to be the safest type in most situations. Is that what you were asking? Otherwise, a heater is a heater is a heater. Many ceramic heaters (of the bathroom-heating variety) also have a level switch and if the heater goes lopsided or tips over it will shut itself off.
