There are two types of heat exchanger that can be present, they are the primary heat exchanger and the secondary heat exchanger. The primary is present in almost all boilers and it transfers the heat from the burner to the water within the system. The secondary heat exchanger is an item that is only found in combination boilers and allows the heat to be transferred between one closed system and another. The Primary Heat exchanger is sometimes referred to as the 'main' heat exchanger or heat engine. The secondary heat exchanger can also be known as the plate heat exchanger or the domestic hot water heat exchanger .
There are two types of heat exchanger that can be installed, 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 multiple closed systems. The Primary Heat exchanger is sometimes referred to as the 'main' heat exchanger or heat engine. The secondary heat exchanger can also be known as the plate heat exchanger or the domestic hot water heat exchanger .
Usually, there are two different types electrode, Ignition electrodes and flame sensing electrodes ,The Ignition / Spark Electrode causes the spark that begins the combustion procedure within the boiler The flame sensing electrodes are responsible for ensuring there is a flame present in the burner. This is an important safety device that makes sure the boiler isn't still supplying gas without a flame .
