i am doing a boiler job with 4 apartments with 5 heating zones and one 80 gallon indirect water heater. all heating zones and the indirect will be zones with circulators. i need 225,000 net btu for the heating zones. the indirect water heater will require 140,000 net btu. i will zone with circulators and a argo control that can prioritize the indirect water heater. if i do the job this way do i still need to add the 140,000 btu to my heating zones load? thanks foy your input.
