The Alpha domestic hot water heat exchanger, the primary and secondary heat exchangers are two different types of heat exchangers that can be found inside the heating system. Almost all boilers have a primary, which is a heat transfer device that enables heat to be transported from the burner to the water in the system. Heat may be transmitted from one closed system to another thanks to the secondary heat exchanger, which is unique to combination boilers.
