The Alpha domestic hot water heat exchanger is the primary heat exchanger and the secondary heat exchanger are the two different types of heat exchangers that may be present.

Heat may be transmitted from one closed system to another thanks to the secondary heat exchanger, which is unique to combination boilers.
