I am doing up an estimate to replace the propylene glycol in a snow-melt system at a self-serve car wash. Went there today on a service call and found that the glycol solution had been freezing. What is the typical glycol-to-water concentration for a snowmelt system? I haven't done one before. I've done the typical 50/50 solution in home heating systems...should a snow-melt system have a stronger concentration?? I used to have a chart for this but can't find it now.
that looks kind of like the chart I used to have. To answer your question, it is a de-icing system for the bays, not a "true" snowmelt. It is worth noting though, that the bays are open on one side and do not have doors of any kind.
Our coldest recorded winter temp was -9 F, our average cold temp is 11 F.
