What it is

The Glow-worm 2000801831 is a plate-to-plate heat exchanger for the Glow-worm CXi range of combi boilers. It transfers heat from the primary heating circuit to the domestic hot water circuit across sealed plates, keeping the two water systems separate.

Signs this part needs replacing

  • Reduced or fluctuating hot water temperature at the tap
  • Hot water runs cold quickly or takes longer than usual to heat
  • Boiler loses system pressure with no visible leak
  • Kettling or unusual noise from the heat exchanger area during hot water use

Before you order

  • Confirm the part number printed on your existing heat exchanger matches 2000801831
  • Isolate power, gas and water supplies before removing the old unit
  • Fitting must be carried out by a Gas Safe registered engineer
