Which could be as simple as propylene glycol, no? Considering that any hydronic system should be buried below the frost line, "freeze protection" should only be a matter of protecting the earth egress, I would think, which in temperate climates, could be as simple as electric heating tape made for the purpose. Also, stick with PEX or other freeze-proof plastics for the exposed bits, and leave the greater heat conductivity of copper for the run below the frost line.
