Pump advice for 180 w/4 penductors


New member
I am currently setting up a 180 AGA. I am planning on using 4 penductors on the return lines and would like to plumb them all on 1 pump.

The current plan is to go with an Iwaki/Blueline 100. I was wondering if a 70 would do the trick, or if anyone out there has any experience with using penductors. Even better, is anyone using 4 penductors in a simillar setup.

Any advice or input is greatly apppreciated.

Thanks for looking
