I want to thank John and HJ for their help - I really appreciate their contribution to this forum.
I felt I should post an update on this situation to share with the others my experience. After all, we are here to help each other.
Since my last post, I had another licensed plumber come out and give me yet another completely different solution. To be honest, I wasn't confident that the three plumbers that submitted proposals knew what to do. While I value John's suggestions highly, I was confused and not sure what direction to go.
I decided to call Bell and Gossett and see if they could help me. They referred me a local distributor who also provides product support. What an amazing resource I discovered! The B&G rep asked me to fax the details of my home and heating system. Within 3 days, he emailed me a list of parts and requirements to rebuild my heating system from scratch. He and an engineer took my data and calculated flow rates, head losses, etc. I'm very confident their solution was well thought out and planned. My advice is if you are lost or want a professional second opinion, do not hesitate to contact the manufacturers. I know at least B&G stands behind their products and for that, I am and will be a loyal customer.
I'm going to start this project this weekend. Please see the plan below.
1. Combine first and second floors into one zone. Additional zone for basement baseboards will be added later.
2. Use 1" PEX with Monoflow tees feeding 1/2" risers to the cast iron radiators.
3. Keep existing 1" main supply and return lines.
4. Replace zone valves with two B&G NRF-22 pumps for each zone
5. Install B&G EAS for air removal.
6. Install B&G Z-2 relay control box for zone control.
