In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Looking for someone to walk me through an upgrade project.
Hi to all
For some reason my 60 year old Holiday Burnham NG Boiler after 22 straight years of worries free use, crapped out on me and I need to replace it. My old system was a 95’ BaseRay cast iron base board shot gun system with one thermostat and one continuous running circulating pump.
I would like my new system to be a Burnham K2-100 four zone, zone valve system with one Alph2 ECM pump.
Zone one will be a high heat (180) in joist pex-al-pex loop.
Zine two will the old Baseray moved to the basement.
Zone three will be an in slab out building.
Zone 4 will be a 50 gal Burnham indirect HWH.
Question .. Setting up a reverse return distribution system using two straight 1" runs down one side of my ranch in the basement and running four 3/4", nine joist bay loops starting at the supply run and ending with the return run for zone one. Each loop will have a diverter T, flow meter/valve and an isolation/purge valve.
Do I need to put in a balancing valve at the end of the two 1” straight runs?
Do I have to put in a zone valve in each of the four ¾” sub loops even though I have a flow meter/valve?
If I can use my flow meters, should they be Velocity or Volumetric?
Looking for someone with smart phone to face time and help me through this project.
Wife is on my tail. Starting to get a little cold here in SE Ohio.
