Head loss Calculation - Pump Sizing - 1 pipe monoflo system

the pump needs to be downstream of the expansion tank.

So in this drawing either move the pump up to the blue line after the expansion tank.

Or move the expansion tank connection to just above the pump where you have it in the drawing.

i've always been thinking that the water tank might be in the wrong place after looking at other people boilers.

its the relationship between the tank and circulator. The tank could be in a number of different places near the boiler. But the pump should always be pulling or pumping away from where ever the tank is located
