Glow-worm Heat Exchanger
Door Seal Gasket

The Glow-worm door seal is a spare part for the heat exchanger of CXI, HXI, Ultimate, Ultracom, Ultracom2, Betacom, Easicom, Eden, Energy, Xtramax, SXI, Ultrapower and British Gas appliances. The heat exchanger transfers heat from a boiler's burner to water.

A primary heat exchanger is found in all boilers and uses heat from a burner to raise the temperature of the water in the system, whereas a secondary heat exchanger is only found in combis and allows heat to be transferred between closed systems. Seals are intended to prevent leaks of water or harmful gases as they pass through the boiler.
