The Trojan Hot-Scot 450 Watt heater is excellent to use inside the access panels on Livestock Waterers or well houses (non-submersible). The heater comes with a built-in adjustable thermostat. The thermostat range is from 30° to 150°F.
3 settings - Low (30°), Medium (75°), and High (150°)
Just plug the heater into a standard outlet, adjust the thermostat, and let it work. When the temperature rises the thermostat will shut the heater off. The heater will come on when the area around the heater lowers in temperature.
Operates on 120-Volt, only 4-Amp required.
