Viessmann has two different types of heat exchangers 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 transfer of 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.
