In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
How do you get the air out of a glycol system? I have a Honeywell/Spirovent air eliminator on the hottest part of our solar install. I ran the system for 24 hours with water only to get the air out, then pumped in glycol to avoid air in the first place. I am running it at 65PSI and keeping the high temp around 150F. I pulled off a sample and it came out frothy! (think a good, rich, German beer frothy).
Will these air bubbles eventually get scrubbed out by the air eliminator? Or should I drain it out and pump it back in to let the air leave? (other brilliant ideas welcome...). I did not pipe in air elimination at the panels, as I was counting on the Spirovent. As a glycol system, taking it down is nearly impossible (and very bad politics with this customer).
