Immersion Heater

Immersion Heater

  • 8700

Help protect your automatic waterer from freezing in the colder temperatures.  This immersion heater is available in 250 and 500 watts as well as 110/220 volts.  It is thermostat controlled for the highest efficiency.  Installation is easy - simply install in the waterer and plug the cable line under the waterer.  

It is designed with the safety of your animal in mind!  The protected feet add circulation and efficiency to ensure maximum heat while safely keeping electrical lines away from your animals.

NOTE: During the warmer months remove this unit from your waterer to help lengthen the life of your heater.  The disc is teflon coated but when emerged in the water, deposits can accumulate over time.  Once it is removed wipe down with a clean cloth and store in a dry spot until further use.

Part numbers: 543, 543-5, 543/220, and 543-5/220
