Hi all,

Piping Buderus gas cast iron boiler in primary/secondary. The manual gives no piping diagrams like on many other boilers. How's this look? Thanks for any feedback.

    Why primary secondary?

    Why not just supply and return?

    Buderus is fine with

    lower return water temps so primary secondary is not used. The design of the return port makes primary secondary piping redundant. Save the price of the pump for the third zone and just pipe it feed and return, unless you have some really cold return temps.
    Cost is what you spend , value is what you get.
