Age Old Pump vs Zone Valve Question (With a twist)

Mudaero Member Posts: 46
Hey all. So I know the basic dynamics of this question but just wanted to get some input. I am rebuilding my hydronic system and it will contain 2 zones (about 30000 - 40000 btu total per zone [cast rads]). I've done this before using zone valves and a single circulator, but am wondering if I should move to 2 circulators this time simply because of the cost. It's actually cheaper initially (not talking life of system, I know pumps will consume more power) to purchase 2 pumps rather than 1 pump and 2 valves. Anybody have any thoughts on this? It seems to be a half-dozen in one hand, 6 in the other kind of issue. Just looking for any feedback. Thanks.
