The main function of a heat exchanger in a heating system is to facilitate heat transfer between two fluids. This is accomplished by allowing one fluid, typically the heating medium such as water or steam, to transfer its heat to another fluid, which could be air or another liquid, without the two fluids physically mixing. This process is essential in various heating systems, including HVAC systems, to distribute heat efficiently and maintain comfortable temperatures in buildings.

Heat exchangers operate on the principle of thermodynamics, where heat flows from a hot fluid to a colder one, optimizing the heating process. By effectively transferring heat, they enhance the overall efficiency of heating systems while minimizing energy loss. This function is critical in achieving desired thermal comfort and energy savings in various applications, from residential heating to industrial processes.
