This Glow-worm 16 plate DHW heat exchanger is a genuine replacement part for Flexicom and Ultracom appliances. The heat exchanger transfers heat from a boiler’s burner to water. A primary heat exchanger is found in all boilers, using heat from a burner to raise the temperature of the water in the system while a secondary heat exchanger is present only in combis and allows the heat to be transferred between closed systems.
Please always refer to the manufacturer’s instructions for the correct application. All parts should be fitted by a qualified plumber.
