High Temp Glycol

[Rob Littiken]

Does anyone know of a source for High Temperature Glycol for closed loop solar hot water systems?

I've been using regular radiant floor glycol, but have read up and should be using High temp 300+ degree stuff. It seems the regular stuff breaks down in solar panels and losses it corrosion control.

Thanks,
Rob

Wow $125 per gallon. That better be some good stuff.

Thanks for the info.
