Abstract: A manifold for the distribution of a fluid in a plumbing and heating system has a tubular shape and defines in its interior a distribution conduit for the fluid. The manifold extends between a first inlet/outlet end and a second inlet/outlet end, both of which are designed to put the distribution conduit in communication with the exterior of the manifold to receive incoming fluid or to send fluid exiting the manifold. The manifold comprises a plurality of branches arranged in series along a longitudinal extension and interposed between the first and second inlet/outlet ends, wherein each branch allows a quantity of fluid to enter into or exit from the distribution conduit.
