So here's how it broke down
-new domestic hot water coil gasket (with new welded stud as I broke one off)
-new taco air scoop and air vent (there was no air control on the system)
-new honeywell mixing valve for the domestic water (with bypass because I like a nice hot shower!!)
-new zone valve and return plumbed in for whatever future project comes my way (i think a garage heater)
-new barometric damper (unit was installed without one)
-new Honeywell R845A switching relay so both circulators aren't running at the same time when not needed anymore
-new Honeywell L6006A for outfire control
-upgraded all the wiring to proper BX
-tons of valves and unions to make servicing a heck of a lot easier
-setup to bring the returns in both sides of the boiler and space for 2 more returns when needed
-standardization of circulator flanges and piping (1 was 3/4" inch and 1 was 1" necked down pipe)
I purged the lines again one more time today and put all the sheet metal on and tied up all the loose ends. Hopefully this will not only have me running a lot more efficient but also make service and maintenance a lot easier in the years to come. I think this weekend I"m going to go and pick up somewhere from 5-6 tons of rice for the bin and then it's time to just sit back and enjoy the fall! Thanks again to the coal community!
