The expansion vessel is a tank that is used to protect closed heating systems from a spike in the pressure. The tank is filled with air that acts as a cushion against pressure surges within the system.
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 .

The pump is located after the primary heat exchanger within the heating appliance and allows the heated water to be circulated within the closed heating system. In combination boilers , the pump is usually found before the diverter valve to allow circulation through the DHW and central heating systems .
