Make sure you have a good battery and don't worry about it is the simple answer.
If you do decide to install one anyway, they're not expensive and it's not that hard to do. The basic/most common ones replace a frost plug, which is a little tin cup near the bottom of the engine, designed to pop first and relieve pressure if your coolant ever does freeze (which I've never seen happen, because.. antifreeze). So it's just a matter of draining your coolant, popping out the frost plug and tapping in the heater. Getting to the bottom of your engine to do this likely won't be fun.
