questions

narrative

• The idea here is that for both the radiant and the baseboard sections operate similarly and independently. Whenever anywhere else calls for heat that(those) zonevalve(s) open(s) and the bypass zonevalve closes. Threeway valves don't seem to be a good idea in cases where there are more than one alternative path.
• Balancing for radiant and baseboard sections would be accomplished statically using ball valves. For these sections balancing only matters when more than one alternative paths are activated at the same time. Lets say the front door section(fr) and first floor bath(ba1) are both calling for heat. Balancing to favor ba1 would leave ba1's ball valve open and fr's zone valve would be closed a bit to send more heat to ba1. Then you would redo the exercise with all three (fr, ba1 and ba2) calling for heat.

questions

• important to have 2 way zones instead of 3 (tob)
• Still has to be balanced (tob)
• re narrative: Is that the balancing you mean?

• The idea is based on not having to have a manifold balanced or additional back pressure from balancing zone valves when only one zone is open.
