Baxi's front cover part is located within the heat exchanger section. There are two different kinds of heat exchangers that can be installed, the primary heat exchanger and the secondary heat exchanger. The primary is present in almost all boilers, and it transfers the heat from the burner to the water within the system. The secondary heat exchanger is exclusive to combination boilers and allows the heat to be transferred between two closed systems.
