ABSTRACT:
An improved animal waterer which prevents ice formation and saves energy through the combination of a top cover, drink tube, and a novel drink float. Minimizing the water surface exposed to the air reduces heat transfer from the water to the air. A drink float allows an animal to drink freely and prevents heat loss. The combination further saves energy, hinders ice formation and inhibits contaminants from entering the water supply. A waterer housing corner guard inhibits the formation of loose animal hair contaminants.
