Different pressure drops through different heat exchangers require different pump head to maintain adequate flow. 2 pumps will be the logical choice.

But if the design (and resistance) of heat exchangers is similar, than we can assume that the same pump will have enough head and flow rate will be sufficient for both loads. If that requirement is met than using diverting valve could simplify your design efforts.

Electronic 3-way diverting valves with spring return 110V/60 HZ actuators now available with Copper sweat and NPT connections.
