Abstract
An animal trough waterer and novel trough heater and thermostat arrangement are disclosed. The waterer includes a trough surrounded by an insulated housing. Attached to the bottom wall of the trough is a bracket which holds the heater in place against the trough. The bracket provides a slideway in which the thermostat is carried in any one of a range of positions. By adjusting the location of the thermostat to the heater, the water can be maintained at a relatively low but even temperature, and heater energy consumption can be reduced.
