This is a standard semi-gravity system, feed and vent each side of the cylinder coil, boiler at ground level.
The pump is in the return, next to the boiler, which I believe is common.
Will I have a problem if the pump is moved to the flow side of the boiler ?
I want to do this so as to improve the head at the suction side of the pump, which is cavitating slightly.
Thanks, pcr.
 
no probs, pumps were only put on the return years ago because the lower water temperature suited the older pumps
