Overview
The Vaillant part is located within the heat exchanger section. There are two different kinds of heat exchangers that can be installed, they are 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 is exclusive to combination boilers and allows the heat to be transferred between two closed systems.
