I have a two-story Cape Cod house with a monoflow heating system. There is a single 1-1/4" black pipe main down the center of the basement, which splits at the end into two 3/4" branches, one for each side of the house. There are monoflow tees that feed the 1st & 2nd floors. Off of each Tees are 1/2" risers to each of the Rads. I want to separate the 7 Rads on the 2nd floor into it's own zone, using it’s own flow control valve and either zone valves or another B&S pump.
1)- Can I change the 2nd floor into to a series loop system by itself (not Monoflow) if I provide its own separate main, pump (or zone valve), flow-control valve and return?
2) - If it has to be another Monoflow branch for the 2nd floor, can I use 3/4" piping for the main feed and the return? Will I disrupt the balance of the entire system by splitting off the 2nd floor, using the existing pump, two flow control valves and two zone valves (one for each floor)?
