There are two kinds of heat exchanger that can be within your boiler, the primary heat exchanger (also called a heat engine in Worcester’s terminology) and the secondary heat exchanger.
The primary is present in almost all boilers and allows the heat to be transferred from the burner to the water within the system.
The secondary heat exchanger is only found in combination boilers, and transfers heat from the primary circuit to the domestic hot water (DHW) circuit.
