Anyone think of using a bunch of hand warmers and comforters around the tank. you can ppick up a bunch of them for fairly cheap and they last 8 hours. just tape them around the outside of the tank down low
Last night I boiled water and put it in Chinese food soup containers and floated it overnight, seemed to help, I'm running tank on an inverter during the day though, if I get power back ill lend it out. Good luck
ive been able to run my generator through out the day but at night i have to shut it off, i taped 2 sheets all around the tank leaving the top of the tank open for ventilation. so i cant run heat in my house over night and the tank so far has only dropped to 75. make sure you tape off every corner and the bottom that way you really trap the heat inside.
