What it is

The Glow-worm Limiter 10L/Min is a flow restrictor fitted to Glow-worm gas boilers to cap the domestic hot water flow rate at 10 litres per minute. It is supplied under part number 0020118164 and is used across the Betacom, Easicom and Ultimate appliance families. Limiting the flow rate helps the boiler hold a stable hot water temperature within its design output.

Signs this part needs replacing

  • Hot water flow rate at the outlets is higher than the rated 10 L/min
  • Domestic hot water temperature fluctuates or runs hot and cold
  • Scale or debris build-up in the limiter causing reduced or erratic flow
  • Whistling or noise from the limiter area during hot water draw-off
  • The boiler struggles to hold a steady DHW setpoint

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Check the existing limiter's flow rating matches 10 L/min
  • Verify part number 0020118164 against the appliance's parts list
  • Isolate the water supply before removal or fitting
