Power outage

[Dr_Hicks]

If it gets really bad you can triple ziplock bag some hand-warmers and submerge them close to circulation, I have done this once when we were without power for 12 hours, I had enough battery back up for a small pump, and the hand-warmers although unconventional do put out good heat.

I used freezer style ziplocks because of the thicker plastic, worked like a charm.

ps...
The warmers need little air in the bag once you get them going, mine lasted about 4 hours each.
