1" Hydraulic Switcher Unit

Hydraulic switcher unit with insulation, to beconnected below the distribution manifold. This device allows the primary and secondary circuits to be disconnected hydraulically, thereby giving allowing greater volumetric flow in the manifold in comparison to the boiler flow.

This isparticularly suitable for use with condensing boilers. In fact if the boiler pump is set correctly this unit can ensure a low water return temperature (always below 57°C – this is the condensing temperature of the steam in methane gas) so increasing the efficiency of the whole installation
