The hot water plant supply sub-loop incorporates a single boiler, flow splitter and flow mixer together with a circulating pump. The sub-loop also includes a scheduled temperature setpoint manager which is set up by default to control the off-plant temperature at a constant 80°C.
The demand sub-loop incorporates a flow splitter and flow mixer in order that the loop can be connected to heating plant components. The image below shows a hot water plant loop connected to 2 water heating coils.
