This is the original model with the same functionality but exposed wiring.
Our product moves water as opposed to heating it. This is about 95% less expensive than heating. The air temperature controlled switch allows the unit to operate only when needed. The switch turns on at 35 Degrees and off at 45 degrees. Our unit attaches to the side of the stock tank allowing for open water where animals need it. This product is a 12v unit. Operates best on 12v 200amp hour solar battery, 110 to 12v converter, or DIY solar kit. All are available with separate pricing.
