Mapping an existing heating system?

Dan_G Member Posts: 32
I have a HWBB system powered by a Munchkin 80M and have easy access to the boiler and all the pumps. However, I have no idea where the PEX is running or which tube/fin units are in what sequence.

Any insight how to trace the system layout?

    Some pics would help

    us to see more of what's going on.

    Do you have a basement with exposed piping, or what can you see? If most of the piping is buried in walls/ceilings that you can't access, you might not be able to do much more than educated guesses...
