Alpha has two kinds of heat exchangers that can be found within the heating unit; 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 only required in a combi boiler and allows the heat to be transferred between two closed systems.
