When do you need a hydraulic arrow to the distribution manifold?
The house has a gas boiler, to which a distribution manifold is connected. Three circuits depart from it. The first - to the warm floor on the first floor, the second - also to the warm floor on the first, second and third floors. The third is for batteries on the second and third floors. Is it necessary to put a hydraulic arrow on the collector with such a scheme?

Hello. If you need to equalize the pressure in the system, then the installation of the hydraulic arm is justified. In addition, water hammer is reduced, it is also worth considering.
Among other things, in your case, you need to separate the three hydraulic flows, which means that the installation of the hydraulic arrow is more than relevant. I advise you to read an article on hydraulics for heating - focus on this material.
