Nice. Okay, so it looks like being conservative and allowing even a 1ft head increase from friction losses, the Taco and Grundfos are close to or above the .03gpm/sqft range. 2.25gpm for panel #2 -> .028gpm/sqft and 3.5gpm for panel #1 -> .041gpm/sqft. And I expect the flow rates will be a little bit higher if only .7ft of head is added.
