Glow-Worm Heat Exchanger 30 Kw 2000801701

Glow-Worm

Glow-worm has two different types of heat exchangers that can be present, 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 between one closed system and another.
