Hello all excited to be here and ready to listen! I have a 2 pipe direct return setup to a natural gas Williamson boiler in my home. I have what I believe to be 3” supply cast iron piping and 2” return piping. I will be doing the work myself. I have a couple of questions.
1st- I’d like to remove the cast iron piping in my basement and replace with copper piping or pex to allow for headroom. Is this feasible and if so what size piping do I need? 2nd- I’d like to create 2 zones for upstairs and downstairs. I’m an HVAC mechanic so I’m not afraid of wiring and installing pumps and zone valves. Again is this feasible?
Sorry for the long post but I’m ready to listen to the pros here and am excited to get started. Let me know what other details I need to provide!!!
