Help sizing a pump
« on: October 12, 2012, 11:57:18 AM »

Hey guys, I have looked online at the charts and such on how to calculate ft of head but for some reason it confuses me.  I'm hoping that maybe you guys could help me out here.  Here is my setup:

I will run from my owb to my shop about 35-40 ft.  (maybe 1" line but most likely 3/4")

I will go up the wall 10 ft and over about 20 ft in the attic.  From there it will go through 2 heat echangers.  They are older and I think the pipe in the coil is like 1/2 or mabye 3/4 so there shouldn't be too much resistance there.  I will go straigt back over and down the wall and back to the wood burner. 

Also, there might be 4 - 90 deg elbows in the system.  I'll go a head and include them for sizing purposes even though I'm not sure if i will use them or not.

Can anybody tell me what pump I would need for this?  I'm trying to keep the cost down as much as possible.  Thank you!

or even better, about how many ft of head that will be so I can look around and different brands?
