Concentrated "arctic grade" anti-freeze solution of virgin propylene glycol with triple protection inhibitor package can be mixed with water to desired protection level.
Not for use in boilers with aluminum heat exchangers
I need to add a small amount of glycol to my system as I was adding a system feeder. Also, my HVAC contractor had done the bare minimum (5 gallons) in the initial glycol fill. From what I read (and based on car antifreeze as an analogy), ensuring that inhibitors in the glycol are compatible means sticking with the same brand and kind.
