I meant to wind up the thread.
Boilers isolated from tank by protection valve cooling.
System filled to 12 psi when cool.
Expansion tank pressurized to ~13 psi.
Isolated autofill valve.
Boilers and recirc loop drop to 3 psi when cooled.
Low head okay since it just recircs til warm.
Boilers come back up to pressure equalization when warming and prot. valve starts opening (130?).
Everything good.
