Re: What do you do with your old coolant? (was: Coolant suprise)

I put it in a 55 gallon drum I have in the basement, and save it for topping
up the hydronic heating system in my house. I have about 100 gallons of
50/50 mix in the heating system, which uses old style cast iron radiators,
some of them pretty big. I live where it can get to 40º below zero at
night, and sometimes I have to leave the house for extended periods in the
winter, so I cannot afford to drain the system as other people do, or to
have it freeze up as the previous owners did. Once you let pipes freeze
with water in them, they get bigger and it is a bear to thread them into new
fittings.

The previous owners, and most people who have these types of systems, put
raw water in them. It turns black with time, but the corrosion isn't too
bad, if you don't drain the system that often. Copper and even iron are
relatively forgiving, as long as fresh oxygen never gets into the system.
With the antifreeze I filled it with, I figure corrosion is just about
halted. The coolant only comes into contact with black iron, brass and
copper, so there isn't nearly the corrosion danger that there is in a modern
automotive engine.

If you turn your antifreeze in to a legitimate recycling center, they purify
the glycol, probably by distillation, put some more corrosion inhibitors in
it, and resell it to you, or more likely to fleet buyers of recycled
antifreeze.
