A solar water heater in an area where the temperature gets below freezing will usually have a closed loop cooling system with an antifreeze solution.
· Glycol/water mixtures
Glycol/water mixtures have a 50/50 or 60/40 glycol-to-water ratio. Ethylene and propylene glycol are "antifreezes." (from EERE Department of Energy)
If NFPA and the California State Fire Marshal believe that antifreeze solutions can result in deflagrations when the antifreeze comes in contact with flaming materials shouldn't these systems be banned as fire hazards.
