What it is

The Glow-worm DHW heat exchanger is a 20 plate unit that transfers heat from the boiler primary circuit to the domestic hot water supply. It is used across the Glow-worm Flexicom and Ultracom boiler models listed below. The plate pack provides the surface area required to bring domestic hot water up to temperature on demand.

Signs this part needs replacing

  • Domestic hot water runs cool or swings between hot and cold
  • Reduced hot water flow rate at the tap
  • Hot water temperature drops when a second outlet is opened
  • Scale or debris restricting flow through the plate channels
  • Primary pressure rise or discoloured domestic water, indicating transfer across the plates

Before you order

  • Confirm the boiler model against the fit list above
  • Compare the plate count and connection layout with the unit being removed
  • Check the system for sludge or scale that may have caused the failure, and flush if required
  • Isolate and depressurise the boiler before removal
