This part is located within the heat exchanger section. There are two different types of heat exchanger that can be present, the primary heat exchanger and the secondary heat exchanger. The primary is present in almost all boilers and it allows the heat to be transferred from the burner to the water within the system. The secondary heat exchanger only appears on combination boilers and allows the heat to be transferred between two closed systems. The Primary Heat exchanger is also known as a "main" heat exchanger or heat engine. The secondary heat exchanger can also be known as the plate heat exchanger or the domestic hot water heat exchanger .
