What it is

The Gledhill XB347 is an overheat thermostat switch for Gledhill flow boilers. It monitors boiler temperature and cuts the heat source if the boiler overheats, providing a safety trip. It is used across the Gledhill Electramate and Gulfstream ranges.

Signs this part needs replacing

  • The boiler locks out and needs a manual reset before it will run again
  • The overheat trip operates before the boiler reaches its normal working temperature
  • Repeated overheat lockouts occur during a call for heat
  • The boiler shuts down shortly after firing
  • The thermostat does not reset once the boiler has cooled

Before you order

  • Match your appliance model against the fit list above
  • Check the existing thermostat is marked XB347
  • Isolate the electrical supply before inspection or replacement
  • Consult the manufacturer's parts list if your model is not listed
