Plumbing a manifold off a 2 pipe forced hot water system

Can anyone post a schematic of a hot water heater boiler with a manifold piped off the supply and returns for 3 zones? I plan on adding in radiant heat for my kitchen and bathrooms separately using 1/2”

    Many of us can. The question is Will We?

    Do you currently have a single zone connected to your boiler?

    What radiators are you using: Cast iron, Copper/Alum fin Baseboard, Convector?

    What radiant heat are you adding: Staple up under the floor, Gyp-crete thin pour on the floor, other?

    is this the type of "manifold" diagram you are interested in?

    From the presentation I used for teaching Hydronics.

    Flo-control on the suction side of the circ? B&G typically shows them down stream? I like you lower temperature placement better.

    Take that up with Dan. He wrote the book I stole it from.

    but don't be too hard on him, he's still learning
