For that heater to work, it needs to be on about an hour or two before you start the engine/driving off, after parking on the open lot at work/mall/grocery store etc when temp is below zero for example.
It can't stay on all the time when engine is off or your battery will be dead.
Now if it's only on when you start the engine and you have frozen water/oil (oil always have some water in it) already, it won't do you any good cause the crank-case presure build right away.
