It’s sometimes easy to think of a radiant manifold as simply a dumb box. One stream of water or other fluid goes in and gets directed to several other areas. Choosing the right radiant manifold isn’t quite as easy as one who holds the belief that manifolds are just dumb mixing blocks may think.
The first thing a contractor may want to consider when shopping for a manifold is to have a plausible layout for the system already in hand. Gary Runyan, Zurn PEX manager of product development and engineering, says this factor can be critical. Zurn PEX makes three manifolds for radiant heat: a stainless-steel model, the QickZone modular manifold and the AccuFlow preassembled brass manifold.
