Some systems run with a single load circulator w/ zone valves and others, like mine, have a taco on all 3 zones. Is it more efficient energy-wise to just use 1 circulator and zone valves rather than 3 pumps?
And is there a limit to the number of zones you can run off 1 circulator, or does it depend on things like length of runs, head, etc..
TIA, Pat
