Worcester Heat Exchangers (Page 3)
There are two types of heat exchanger that can be fitted, 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 from one closed system to another.
