Glycol questions
Is there a practical difference between "food-grade" glycol and "automotive-grade" for a home installation (i.e., one without city inspectors)?
What is the proper glycol/water mix?
Is it possible to control the pump speed on the 1/3 hp power pack to reduce power usage? I only have a 25 foot run and it seems like it shouldn't need to move as much coolent as with a longer run.
Thanks,
Scott Erie
