I guess I would need more info like the size (net) btu of boiler. This is the first step on determining how much flow is needed. Secondly, Total pump head will need to be checked, and lastly: Your boiler must be able to satisfy the total load with all zones calling. All this info can be obtained from B&G.com fairley easily. I believe that you may have found primary/secondary pipping to be more to your advantage.
