What it is

The Glow-worm 0020118147 is an 8 litre hydraulic block used on Glow-worm Betacom and Easicom boiler ranges. It forms part of the boiler's hydraulic circuit and carries the diverter valve assembly that switches the appliance between domestic hot water and central heating operation.

Signs this part needs replacing

  • No domestic hot water while the boiler still fires for heating
  • Boiler fails to respond to a hot water draw-off, or runs heating when hot water is demanded
  • Radiators stay cold in heating mode despite the boiler firing
  • Water weeping or staining around the hydraulic block or its seals
  • Repeated diverter or flow-related fault codes on the boiler display

Before you order

  • Confirm your boiler model against the fitment list above before ordering
  • Check the part number on the existing hydraulic block matches 0020118147
  • Verify the block is the 8 litre variant, as other capacities are not covered by this part number
  • Inspect the seals and connections on removal and replace any that are perished or damaged
