.....correct line size and pump size wins out everytime.....
Absolutely. Like I said before, I'm trying the two pumps as a band-aid. I hope to get things set up correctly next summer. I just don't have the time or $ right now to pull and replace the lines. Once I do get it set up right, at least I'll have an extra Taco 009 on the shelf for backup.
Ghitch, I absolutely respect and appreciate your experience and input. I'm trying your suggestion (from another post) about decreasing the flue outlet size to 4". I'm anxious to see if it helps with my wood usage. Thanks for your input!
