For that reason a mixing valve (V2) is introduced to blend Most important water through the central plant with return drinking water from the dwelling heating program, therefore allowing for the HIU to satisfy differing demands dictated by DHW and Room heating. On top of that, A 3 port control valve is required to divert movement amongst the DHW plate heat exchanger and dwelling heating circuit; this valve is managed over a very hot drinking water priority foundation. An illustration of the method is proven in Figure 3.
