1. Manifold (1) for the distribution of a fluid circulating in a plumbing and heating system, having a tubular shape and defining in its interior a distribution conduit (2) intended to be crossed by a fluid, the manifold (1) extending longitudinally between:
a first inlet/outlet end (3), suitable to put said distribution conduit (2) in communication with the exterior of the manifold (1) and configured to receive fluid entering the manifold or to send fluid exiting the manifold;
a second inlet/outlet end (4), separate from said first inlet/outlet end (3), suitable—at least in an operating condition—to put said distribution conduit (2) in communication with the exterior of the manifold (1) and configured to receive fluid entering the manifold or to send fluid exiting the manifold;
wherein the manifold (1), in use, is configured to operate with at least one of said first inlet/outlet end (3) and second inlet/outlet end (4) which receives fluid entering the manifold or sends fluid exiting the manifold;
the manifold (1) being provided with a plurality of branches (5), mutually distinct and arranged in series along a longitudinal extension of the manifold, interposed between the first inlet/outlet end (3) and the second inlet/outlet end (4), wherein:
the plurality of branches (5) comprises at least a first branch (6) and a final branch (7);
each branch (5) of said plurality of branches defines a respective branch point of the manifold, at which a quantity of fluid in transit in the distribution conduit (2) can exit the distribution conduit towards the exterior or a quantity of fluid coming from the exterior can enter the distribution conduit;
each branch (5) of said plurality of branches comprises at least one respective first access or exit opening (8), configured to allow the exit from the manifold (1) of at least part of the fluid in transit in the distribution conduit (2) or the entrance of fluid inside the distribution conduit (2), said respective first access or exit opening (8) being a hole having a respective axis (D) of the branch;
and wherein the branches (5) of said plurality of branches are positioned, in the manifold (1), in such a way that:
the distance between the first inlet/outlet end (3) and the axis (D) of the first branch (6) is equal to an initial stretch (X) of the manifold;
the distance between the axis (D) of each branch (5) and the axes of adjacent branches, and/or between the axis (D) of the first branch (6) and the axis of the subsequent branch and/or between the axis (D) of the last branch (7) and the axis of the previous branch, is equal to a given centre-to-centre distance measurement (A) between the branches (5) of the manifold;
the distance between the axis (D) of the last branch (7) and the second inlet/outlet end (4) is equal to a final stretch (Y) of the manifold; and
wherein the length of said final stretch (Y) is equal to the sum of the length of said initial stretch (X) and N times half of said centre-to-centre distance measurement (A), where N is an odd integer greater than or equal to 1.
