I need to replace the heat pipes for a small apartment building. Each unit will be on a separate circuit for zone control. I have a procedure, but it seems very approximate.
Do you know of a reference that would help me determine the flows in each segment for a particular head pressure...
I want to replace most of my existing black iron hot water heating pipes to divide the system into zones. Is it OK to use copper pipes to connect to my cast iron radiaters and to iron pipes? Do I need to use dielectric unions?
