I am building a multi-zone hydronic system and am wondering how far the supply and the return lines (3/4") should be spread apart where they meet the main loop. I am using a 1-1/4" main loop and there are 6 zones coming off of it eash with its own Grundfos UPS15-58 circ pump.
I have heard that the reducing tees should be no less than 8" apart. Some other site suggested 4". Can someone elaborate as to why this distance is important. I assume it is so that there is no crossover pull from the cold water side.
What is the proper separation distance for the tees.....? How far apart can I put the tees and maintain effectiveness.??
THANKS
