amine the diagram shown below and we will try to perceive what happens as the pumps are activated. The most important thing to consider when measuring interferences between different circuits, is to determine how pressure, net the height difference, varies between the two manifolds. We will refer to this pressure difference as ∆P.. When installing a low-loss header, system mixed supply temperature (T3) must be calculated as follows: The temperature sensor connection [TS] typically located at the top of the low-loss header ensures low return tem-peratures to the boiler at all times and increases opera-tional efficiency. In addition, the low-loss header helps eliminate air and

The low loss header acts as a ‘hydraulic brake’ to manage the speed of the flow, and only the water/flow required for the secondary circuit (s) is carried through. The low loss header will take any excess capacity from the flow, and return it into the primary circuit. This allows boilers to operate at a constant flow rate in the primary.
