Moving the Grundfos UP 15-42fr
I'm installing a Superstor Contender. The old set up has the circ on the return from the indirect. I'd like to move the circ to the hot supply from boiler side. The expansion tank over the boiler is also on the return side but I have no air issues so I do not plan to move it. I am well aware the circ should be moved but I'm not sure if moving it will upset a system that has been working well for 20 yrs. A could use a little guidance please.
