I have a boiler with 3 zone valves on the return side. Also on the return side of the boiler is the circulator pump. Im removing all the baseboard from 2 of the zones and installing radiant heat for those 2 zones. Im not familiar with hooking up the radiant heat with the circ pump and zone valves on the return side. There is no by pass now and want to install one so the water doesnt come back to the boiler so cold. Whats the best way to pipe this off the boiler?

    May I suggest

    Some excellent reading material offered on this site. Pumping away, is one

    You will need to pipe boiler primary secondary, and install a mixing device for the radiant emitters. Also a delta p circ or a differential bypass valve for the zone valves.
