What it is

The Glow-worm thermostat for the immersion heater is a control component used on Glowworm Clearly Solar appliances. It regulates the immersion heater so stored hot water is held at the set temperature rather than continuing to heat. The part is identified by Glow-worm part number 0020103180.

Signs this part needs replacing

  • Domestic hot water runs hotter or cooler than the temperature set on the control
  • Water reaches scalding temperature and the immersion heater does not cut out
  • No hot water is produced even though the immersion heater is switched on
  • The thermostat dial or spindle turns without any effect on the stored water temperature
  • The overheat cut-out operates repeatedly and the immersion heater will not stay running

Before you order

  • Confirm the appliance model matches Glowworm Clearly Solar
  • Compare the part number on the existing thermostat with 0020103180
  • Check whether the thermostat alone is required or whether the wider immersion heater assembly is being replaced
  • Isolate the electrical supply to the immersion heater before carrying out any inspection
