In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
you will go with one-pipe monoflo setting or two-pipe reverse return setting?
Finally I am ready to call in plumbers for their quotes on my gas hot water heating system upgrade. It is a big job with some of new CI baseboards being added and add a new zone for the unfinished basement (framing is in progress).
The attached pdf file is my 3 yrs old Alphine gas boiler's setting. There is a separated boiler circulator. Is this setting a primary/secondary setting (just curious)?
Another attachement is my house floor layout drawing and the existing heating pipe setting.
My house is a ranch house. First floor has a big family room need to be added into the water heating system. A new zone for full basement will also need to be added into the water heating system. The existing main pipe is 1" pipe. All baseboards are and will be CI.
If you were me, you will go with one-pipe monoflo or two-pipe reverse return?
