This is why a mixing valve (V2) is released to blend Most important water with the central plant with return water through the dwelling heating system, thereby letting the HIU to fulfill differing demands dictated by DHW and Area heating. Also, A 3 port Manage valve is needed to divert stream in between the DHW plate heat exchanger and dwelling heating circuit; this valve is controlled over a hot water precedence basis. An example of the system is shown in Figure 3.
But using a centralised plant making use of Heat Interface Units significantly minimizes these concerns, enabling for the quantity consumed by an individual assets to generally be recorded and billed appropriately.
