I need help with a plumbing application on a Verticall and Horizontal Hybrid.....I have 2 Horizontal Loops 600ft in length each. (3/4" IPS) which could easily be handled with a reverse header plumbing application and a single circulator pump.....what would be the best way to incorporate the the 200ft vertical closed loop plumbing into the equation. Can this be done with 1 or 2 Circulating pumps? If so how should I go about plumbing this application and still have even flow through the all the loops. Any basic diagrams will help.
