Thanks for the input. To answer your question, one pump.

But the plan is to run the loop ends into an input mainfold and an output manifold, that will give me the low-velocity I want at the flowrate I need, and also the reduced pump power. I'm figuring a 60 watt pump should do it.

So, I figure I'll buy or braze up a couple of copper manifolds with capacity for three loops. If you look at the loop field diagram, I left space for eight more holes (actually seven, I'll have to find a home for the eighth one).

I may opt for a multi-speed pump at some point, too... It would be cool to have the pump speed auto-selectable, depending on demand. But there is a lot to do before refinements.
