There are two different kinds of heat exchanger that can be present, they are 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.

There is some damage to one of the pipes, this has been shown in the photos. Will NOT affect the use
