Summary for alkaline zinc bath heating Discussion
The thread excerpt provided does not include the actual discussion, only the title and site footer, so the only confirmed topic is ideas for heating an alkaline zinc bath. No specific methods, temperatures, equipment choices, or cautions are visible in the excerpt, and no answerer’s technical advice can be attributed from the text shown. Based on the available source, the page appears to be a Q&A about practical ways to heat an alkaline zinc plating bath, but the substantive recommendations are not present in the excerpt. Because of that, any detailed summary would risk inventing facts not supported by the source.

Q. The cold nights are taking our zinc bath below 70 °F. The bath chemical rep says we need to be at 70 °F min. but preferably over 80 °F. Our bath is cooled for the summer heat but no way to easily switch that to heat.
Would an immersible bucket heater(s) work in the bath or would they slowly dissolve?

A. Hi Mike,
Most bucket heaters seem to be aluminum and they’d rapidly dissolve.
If your cooling system involves a reservoir tank, you could put the heaters in there, where they’d be exposed only to water and possibly antifreeze. But be very careful of any sort of electric heater in a plastic tank; they are by far the biggest cause of plating shop fires, so I would suggest using only heaters made for plating tanks, which will include reliable liquid-level and over-temperature cutouts.
Luck & Regards,
