It has a slightly higher heat capacity than water. It also kills life, so its perfect to prevent algae and stuff in the system.

Or are most ammonia compounds corrosive?

I really have trouble believing that people no longer look at simple things like, putting in an anticorrosive when they are mixing metals.
