This unique product is designed like a traditional plastic poultry fountain but has the added benefit of being able to use it during the winter. The base has a 100 watt thermostatically controlled heater built into it. During the winter, simply plug an extension cord into the base and the unit will work automatically, keeping the water in the 3 gallon reservoir from freezing down to 0F. It has a unique bottom-fill feature, and is ideal for year round use.
