I'm looking for a cheaper place to buy propylene glycol antifreeze. Our current supplier sells it for 10.50 per gallon. Any input would be appreciated.

I do not think it's any cheaper, but I prefer to use Cryo-Tek.
Have not bough it in a while, but if memory served I got it from a Ferguson; DO NOT put RV anti-freeze into your radiant system (there is antifreeze specifically designed for radiant applications)

Out of curiosity, why not?

RV anti-freeze has different additives in the mix, then say an anti-freeze fromulated for a radiant application. Now I am not a chemist or anything, but I think its the fact they add certain chemicals so that the glycol does not "Sour" during the repeated heating and cooling (this is why glycol in solar panels should be flushed and refilled every 3-5 years, heating glycol to near its boiling point breaks down the checmicals and causes the pH to spike and glycol to break down -> meaning no more freeze protection, or at least not as well as when you started).
**This is information is specific to Cryotek (other brands are out there I know, just happens to be the brand I use), they have "TRIPLE" protection; Acid neutralizer, Scale inhibitor and Chelate agent (to inhibit the formation of scale and sediment). BTW I have no idea what a chelate agent was either, until I looked it up & I still am not 100% sure what it is.
