Existing Return Sizes a Problem?
I’ve been working (I think) toward zoning with two circulators. I was reading a bit on primary-secondary piping and am a little concerned having seen this image in connection with a ‘do not’
It’s an existing system so the pipes currently for the return look like this (and I’ve tried to label the pipes based on the Zone they would end up being a part of based on the re-piping I have planned for the supply with the two circulators.
Is it true this looks problematic? My boiler has to take a 1 1/4” return line and I can’t do much about the original line sizes running through much of my house. Should I boycott zoning with circulators at this point?
Blah. So new at this. You guys have been so excellent answering daily to help!
