Worcester Bosch Heat Exchanger Front Cover Shield 87180038360

The Worcester Bosch heat exchanger front cover, part number 87180038360, is a shield that fits to the front face of the heat exchanger on a range of Worcester Bosch gas boilers. It is listed by the manufacturer under the insulation, heat shields and firebricks spare part group, so its job is to protect the heat exchanger body and the surrounding combustion area from direct heat and to keep the heat path contained.

The heat exchanger itself is the component that moves heat from the burner into the water circuit. On a primary heat exchanger the burner raises the temperature of the water in the heating system; a secondary heat exchanger is found on combi models and transfers heat between the two closed circuits. This cover is the shield that sits over the front of that assembly and is used across the Greenstar, Greenstar ErP, RD Series and CDi Series families.

• Visible scorching, charring or blackening across the face of the shield
• Cracking, crumbling or flaking of the shield material
• Distortion or warping of the cover where it meets the heat exchanger body
• Corrosion or rust staining around the cover and the adjacent casing
• Heat damage to nearby components that the shield is meant to protect

• Check the appliance GC number and model against the compatibility list, as this cover is used across a large number of Greenstar, Greenstar ErP, RD Series and CDi Series variants.
• Confirm the part number on the existing component or in the appliance documentation matches 87180038360, and note the alternative number 1020073.
• Have the boiler model and serial number to hand when ordering so the correct variant is supplied.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
