Best answer: Typical radiant baseboard heating systems are divided into zones, and each zone has its own supply pipes and its own thermostat which controls a valve that opens and closes to allow the water to flow or not.
To include more than one zone on a floor, to control specific room(s), could be done, but is complicated. it would be much easier to do it as a building was being built than to add it on later.
What I would envision is a pipe going totally around the perimeter of the building. At each room, there would be a valve that fed into the pipe that would go through the room, reconnecting to the main pipe with a junction.
Ideally, perhaps, the supply pipe could be under the floor with the diversion valves connecting to a pipe going through the floor into the room above. T the point where that pipe exits the room and comes back through the floor, it would connect back with the main supply with a simple T or Y joint.
The valve would need to be able to allow the water to either just flow through, or to redirect ALL of the water from the main line into the separate room line. That valve would be controlled by the thermostat for that room, and the valve would need to connect to the main pump. If the pump was not turned on, it would get energized when the valve was opened.
For however many rooms there were on that level, if none of them were calling for heat, then the pump would be off and there would be no water flow. As soon as one thermostat calls for heat, the associated valve opens, causing the pump to turn on. That will pump water through the main pipe, with a diversion through the one room needing heat.
If another room thermostat calls for heat, then the valve for that room opens and shunts the already flowing water into that room as well. Since the pump would already be running, the second valve opening would have no effect on the pump. However, it would need to be able to keep the pump running if the thermostat in the first room stops calling for heat and closes its valve.
.... and so on for any other room that called for heat.
I am not a heating system installer, but we have a 2 zone hot water baseboard system in our house, and I watched the contractor put it in. Conversations with him over the two weeks or so that it required were quite enlightening.
I <<think>> something like that would work.
