Offer your livestock and animals ice-free drinking water all winter long. Thick winter ice may deprive your livestock of the water essential to their health and survival in extreme cold. Stock tank deicers keep ensure a supply of ice-free water for your livestock. When used properly, a deicer will raise the temperature of the water surrounding the heating element to a temperature slightly above freezing in order to maintain a portion of drinking water. This allows your livestock to have water available when they need it. Many heaters and de-icers are thermostatically controlled to operate only when the temperature drops below freezing. This saves energy, creating a practical solution to the problem of offering drinking water in the harsh winter cold.
