Let's say for the sake of discussion that Water Wetter really did what it claims to do.

Would you REALLY want it to run the system COOLER?

Various systems under the hood require a given temp. in order to operate properly. If that temp. is not reached, could these systems be hampered by a system that's now running TOO cool?

Who knows?
