Heat exchangers can be split into two categories, primary and secondary. The primary is present in almost all boilers and can sometimes be called the main heat exchanger or heat engine. The secondary heat exchanger is only found in combi boilers and can also be known as a plate heat exchanger or hot water heat exchanger. The primary heat exchanger is used to increase the temperature of the water in the system by transferring the heat from the burner. The secondary heat exchanger allows the transfer of heat between two closed systems .
