To preface I'm new to this. This is my second winter with animals and by far the hardest winter I've experienced in 10 years. We have a 100 acre stead in the Northeast. It hasn't been above freezing since the beginning of December. Nights are even touching subzero (F). At this point stock tanks are nearing 20% capacity. We use the plastic Rubbermaid ones in 100 & 150 gallons. Absolutely no power to the animals and the house is about a quarter mile away. We haul water in. What can we do to keep tanks from freezing or even thawing them easily? We have a genny but I don't exactly want to run it 24/7 just to maintain. I ran a 12v diesel heater off a deep cycle plummed into a plywood lid. That wasn't awful. Now I'm considering a wood fired stock tank heater. To at least thaw once a week or so to increase holding capacity. I attached a rough pic of the idea. But at this rate I'll try anything. #home source
