I can't take credit for any of the piping or much else....
I'm just the wiring and start up monkey!
7- Callefi "pop top" zone valves
2- Honeywell Wireless Pro6000 tstats
5- Honeywell Pro5000 tstats
Grundfos Magna System Pump
100+ gallon indirect tank
Don't have any before pics, sorry. It was originally a cast iron boiler (constant temp) with 4 zones (pumps). We re-piped the entire boiler room and split up the system to make 7 zones as the four apartments upstairs were originally controlled by only 2 thermostats and two of the retail shops downstairs were controlled by 1 stat.
I thought this job turned out pretty well considering it was a bit of a rush.
