This part is located within the heat exchanger section. Heat exchangers can be split into two different types, primary and secondary. The primary is present in almost all boilers and can sometimes be referred to as the main heat exchanger or heat engine. The secondary heat exchanger only appears in combi boilers and is sometimes called the plate heat exchanger or hot water heat exchanger. The primary heat exchanger allows the water in the system to be heated by transferring the heat produced by the burner. The secondary heat exchanger allows heat to be transferred between two closed systems .
