+++ Only error, move the expansion tank to the other side of the circulator so the circulator pumps AWAY from the expansion tank, so the pump can PUSH water at its high head into the boiler:
Read the ENTIRE series design steps:
: I don't need the system to do very many gpm, so would this pump be adequate to pump into the boiler?
+++ Yes, as the pump is a variable speed,
the model can serve for both the boiler side of the low loss header and the radiation circuit side, keeping the same circulators for simplicity.
Be sure to include balancing valves in the 1-1/4 circuits to adjust water flow as needed in the individual circuits:
