No such thing as temporary winterization of water lines. Either you blow em out or add antifreeze or you didn't Winterize them.
You're in the worst area for lack of winterization issues. More cracked boat motors and rv pipes where it "almost" gets cold nough to Winterize than up north where you know it'll freeze or Deep South where you know it won't.
Heated hose? not needed unless you want to leave it hooked up and water stagnant. Let the water drip somewhere will keep it thawed in cool weather like that.
Sounds like a great place to spend the winter!
