I'm considering buying one of those large 300 gallon water tanks to store water in at my property. I'm creating a gravity fed system by putting this on a raised platform and then feeding down to our cabin.
My problem is that I can't figure out how I'm going to keep the water from freezing in the winter. I've thought about building an enclosed box frame and insulating but I'm not sure if insulation is enough to keep me liquid. I've thought about heat tape but that's a lot of heat tape to buy and a lot of electricity to keep it going.
Anyone have experience with this sort of thing?
