Glow-worm are two kinds of heat exchanger that can be fitted, 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 only appears on combination boilers and allows the heat to be transferred from one closed system to another.
