In northwest Nebraska, we get some brutal temperatures that can cause major freezing of livestock tanks. To prevent this, I decided to insert a 10-foot-diameter tank inside a 12-foot tank. I placed the opening of a small cutout in the 10-foot tank against an inlet pipe that comes from our house’s “pump and dump” HVAC system. By way of the design, the gap around the outside of the 10-foot tank allows warm water to flow around the tank, keeping the water open for livestock. If only one side of the tank is needed, I insert a grooved baffle.
