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 most boilers and can sometimes be referred to as the main heat exchanger or heat engine. The secondary heat exchanger is only found in combi boilers and can also be known as the domestic hot water heat exchanger or plate heat exchanger. The primary heat exchanger is used to increase the temperature of the water in the system by transferring the heat from the burner. The secondary heat exchanger allows heat to be transferred between two closed systems .
