hydronic system antifreeze

bill_67 Member Posts: 29
seeking opinions on putting ethyl-whatever in hydronic systems,several customers have asked me to do it as they leave town alot in winter, i am somewhat new and asked for
thoughts at a large plumbing and heating serv. i get parts from in a larger city,both techs who were not young guys (experienced looking)
said that ethyl-whatever eats seals and solder,this seems
odd, any thoughts are welcome.
