What is the primary function of a heat exchanger?

The primary function of a heat exchanger is to transfer heat from one medium to another without mixing them. In the context of oil burners, the heat exchanger plays a crucial role in transferring heat generated by the combustion of fuel oil to the heating medium, typically water or air. This process is essential in heating systems, as it allows for effective and efficient distribution of heat throughout a space.

The efficiency of the heating system largely depends on how well the heat exchanger performs this function, contributing to the overall effectiveness of the HVAC system. By ensuring that the heat is properly exchanged, the heat exchanger plays a vital role in maintaining comfortable indoor temperatures while optimizing energy use.
