I drain mine and leave it in... There should plenty of room inside the HW tank for expansion from any small amount amount of left over water in it.
I am planning on installing a 120VAC low wattage Electric heater core in this spot pretty soon when I start playing with my Hydronic Heating System changes so this may change my winterizing methods. My hot water heater is presently propane gas only...
