Help with using Navien in a primary/secondary loop
need to circulate up to 20 gpm in open radiant system thru a Navien NPE 240 A (rated for 4 gpm)....can I use a manifold loop to create a primary loop for the navien and then run the radiant system as a secondary loop
this is my first time here...I could do a drawing of the whole system and scan it in I think...
