ABSTRACT:
A method and apparatus for heating an animal waterer of a type having an enclosed housing with a plurality of nipple valves extending outwardly of the housing for allowing animals to drink directly therefrom. The heat sink coupling is disposed interiorly of the housing and is connected to a water supply line at one end and a nipple valve at the opposite end. A rigid heater and a control means for such heater contacts the coupling; and heat is supplied to the coupling when the heater is activated. The control means senses the temperature at the outer surface of the coupling in the vicinity of the seating surface of the nipple valve and activates and deactivates the heater based on such temperature.
