Vaillant has two kinds 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 heat to be transferred from the burner to the water within the system.

A Vaillant connecting piece supplied with clips, O-rings and screws for use in the heat exchanger of THERMOcompact VU (fan-assisted), TURBOmax VUW (fan-assisted) and aquaPLUS VUI (fan-assisted) boilers.  The heat exchanger transfers heat from a boiler's burner to water. A primary heat exchanger is found in all boilers, using heat from a burner to raise the temperature of the water in the system while a secondary heat exchanger is present only in combis and allows the heat to be transferred between closed systems.
