Often used for temporary heating in sinks and pails, these heaters have a circular base that sits at the bottom of containers to quickly and efficiently heat liquid through direct contact. Remove them from the container after heating its contents. Heaters require a temperature switch or controller (sold separately) to regulate heat output. The heating element is Incoloy for excellent corrosion resistance.

Note: Immerse the heating element in liquid up to at least the minimum coverage level to prevent heater failure.
