Owners of livestock have to worry about water for their animals during the winter months. One of the solutions is to put a heater in the drinking water tank, this helps keep the water warm and prevents it from freezing during winter months. This solution requires electricity to power the heater.
A more modern and efficient system is a Livestock Watering Fountain. This is an engineered insulated device that keeps the water from freezing without the used of electricity. Please watch the following video to see how it works.
