Adding 3rd Zone - Circulator Question

I have been trying to find a guide or information on design for adding a new zone however I have not been able to find anything. I have a home with, Basement, 1st FL and 2nd FL.

The Basement has its own zone, and the 1st and 2nd FL share a zone. I want to make the 2nd FL its own zone.

I have 1 Pump circulator for all these zones on my copper piping. The copper pipe branches out for the basement, and the rest leads up for the rest of the house. Almost like a fork in the road.

Is this correct design? I would think each zone should have its own circulator pump. If the second zone is branching off, the copper pipe is not closing off. There must be heat that is being filtered through this area.

Please let me know or point me to somewhere I can read about proper design to get the most efficiency.

When you say 'zone', does this mean that each floor has it's own thermostat?

And that there are electric zone valves on the pipes leading to each floor?

I don't think you are saying that... it sounds to me as if your system is all ONE zone, with three parallel LOOPS heating each floor simultaneously...

Is that accurate?
