The secondary water is filtered and decontaminated, enters the heat exchanger via circulation, and is heated by steam or high temperature water to supply heat. After the steam or high-temperature water enters the plate heat exchanger, it turns into condensed water or high-temperature return water to return to the heat source, and performs loop circulation of the primary and secondary heating systems. The make-up pump pumps soft water into the system to keep the system pressure constant.
