If the tank is empty for all but a small bit at the bottom, and (this is critical) no pipes still have or will have water in them, and all valves are open, then you should be ok. A shop vac is your friend when it comes to making sure that lines are dried out. Works wonders for that last bit in the bilge and the ice box too. Those last little bits of water are much more likely to be responsible for obnoxious scum than freezing damage in my opinion, but still a good reason to dry them out if you can. The potable water system is less likely to contain nutrients for slime causing bugs. The ice that forms from very small amounts of water remaining in the bottom of a container, and the expansion of water as it approaches plus 4 degrees Celsius, is not like the pack ice that crushed the Endurance. It needs to be confined in some way to cause damage. The confinement can come from ice as it forms, and so the danger from water remaining in lines or in pumps, but a tiny bit in the bottom of a tank or muffler would not cause me concern. Maybe it should, but if that is the case then I have been lucky. I got sick of the taste of plumbing antifreeze early on too. I don't know why you would have rubber parts in a hot water tank, and barring that I don't see how pure alcohol would hurt, but I agree with the other comments that suggest that it is probably a waste of good booze.

The drain in not quite positioned at the bottom of the tank so there is always some residual water left in the tank and although I leave the drain valve open for expansion I am concerned that any freezing could damage the tank connections. Any advice would be appreciated.
