Hi All, I was wondering if anybody has a diagram / suggestion on how to construct a freeze resistent livestock waterer using ground heat instead of electric . years ago ,a rancher described a system he built using a large concrete pipe [3 ft ] installed vertically about 5 ft deep , set a tank on top, both the perimeters of the tank and pipe were insulated , and the open top of the tank was partially insulated with a hot tub floater blanket. With the adding of water on a regular basis , this seemed to work ok depending on how much water was added and how severe the weather In my case , there won't be much water consumption, but installed inside of the barn ,so there won't be wind issues , I'm thinking of installing a 12v valve in the ground heat pit and over flow drain to add water on a timer to suppliment ground heat and keep water fresh If anyone has any ideas that could lessen the learning curve on this project I would be thankful
