I’m looking for a food grade Boiler Antifreeze. Will this product work?
No, our Chemworld Boiler Antifreeze is not food grade. Your food grade options would be Propylene Glycol USP or Dowfrost Inhibited Propylene Glycol.

Your Boiler Antifreeze says 1 gallon makes 2 to 5 total gallons of Antifreeze. I have a 500 gallon boiler and I need at least a 30% concentration. How many Gallons of Antifreeze would I need to do that? 150 Gallons of Antifreeze are required to get your system to 30%.
