I have about a 100' run from my boiler to my indoor boiler, flat ground, 1 inch id pipe, 4 elbows, and I have no idea what I need for a pump. Can anyone help me out.

I prefer the Grundfoss 26-99 three speed cast Iron, set the speed to your heat load on temp differential!
-
Thanks Slim. So start it out slow and if I am noticing a need for more heat in the house turn it up.

You've got it, this is where the temp gauges come in handy on all 4 ports, ideally you can keep temp differentials under but close to 20 degrees across the heat exchanger supply and return under full load.
-
Slim which 4 ports are you talking about? ON my system I have one 60 plate heat exchanger that handles all of the heat transfer.

Slim is talking about the 4 port on your 60-plate HX. So you can moniter Supply and Returns for both Radiant system and OWB ;D

OK thanks LittleJohn. That is what I was thinking, just wanted to make sure.

Thanks Littlejohn, I'm busy welding up this darn boiler/ burning myself up and didn't see the post
