The Farm Innovators heated waterer holds a generous 2 gallons of water. While convenient for winter conditions its efficient design makes it perfect for year-round use. Designed to be hung or set on the ground, there are 3 drip-free and freeze-free nipples distributed evenly around the drinker. Removable cover for easy filling. The built-in 60-watt heater is thermostatically controlled to turn on or off automatically.
