I have an older solar space heat system using Bray oil as the working fluid. (An antifreeze/anti-corrosion water mixture is the storage medium.) I have a leak somewhere and have noticed a slight "hot engine" odor lately (several months now). Is this the Bray oil or the tank fluid? What is it's health effect? How much should I be worried? Thanks for considering this.
