SUMMARY
In a closed water heating system utilizing a heat exchanger for district heating, the optimal position for the circulator is before the heat exchanger. This configuration minimizes thermal cycling on the pump when hot water is drawn on demand, thereby enhancing the longevity of the system. Additionally, it is crucial to ensure that the circulator is installed with the expansion tank connection on the suction side to maintain proper system pressure and function.
