Title: pump size
Post by: dmiller on October 03, 2013, 05:07:43 PM

I have 200ft of closed loop to a heat exchanger with the option of adding a brazed plate exchanger.  What size pump do I need and does it need to be a three speed.  My pex is 1in

A Grundfos 15-58 or equivalent pump should be fine.
You may want to go with a 30 plate if you do add one otherwise you will be pretty close to the limits of the pump.
