I'm looking for some piping diagrams for a outdoor wood boiler connected through a heat exchanger into a oil fired system. Any help would be appreciated.

    from Caleffi will be out in a few weeks. it is an issue dedicated to BIO and wood fueled boilers, including OWF un-pressurized types.



    We recommend isolating the OWF from the hydronic system with a properly sized heat exchanger. Pipe additional boilers in parallel to eliminate circulation thru them while they are off line. An exception would be a boiler with a tankless (thankless) coil providing DHW.



    Another common mistake is under sizing the piping from the OWF to the building. Spend the money to size and insulate these lines properly to prevent "thermal constipation" and excessive energy loss.
