The Halstead Flow Manifold part is based around the diverter valve section. The diverter valve is a directional water mechanism that only appears in combi boilers. It allows the hot water to be directed to the heating system or to the hot water system. This feature is what separates a normal boiler from a combi boiler due to the fact that the boiler can provide hot water and heating without the need for a cylinder.
