Not extra complexity at all. Just a pump and flow and return for the

But still needs an extra pump, surely??

That is not extra complexity at all. Pumps are about the same price as zone
valves. You could use the one pump and a three way valve and arrange the
piping accordingly, but that "is" more complexity.


OK. That's what I imagined.
