What it is

The Gledhill GT198 is a domestic hot water inlet and outlet sensor used on Gledhill thermal store and boiler appliances. It monitors water temperature at the DHW inlet and outlet points and feeds that reading back to the appliance controls. It is listed under thermostats within the Gledhill spares range.

Signs this part needs replacing

  • Domestic hot water runs hotter or cooler than the set temperature
  • Hot water temperature fluctuates between draws without any change to settings
  • The appliance fails to fire or cuts out when hot water is demanded
  • Inconsistent or implausible temperature readings at the controls
  • Hot water performance changes after the sensor or its wiring is disturbed

Before you order

  • Confirm your appliance model against the fit list above
  • Check the existing sensor is marked GT198, or that the manufacturer's parts list gives GT198 for your model
  • Establish whether the inlet or outlet sensor position is the one at fault, as the same part is used at both points
  • Inspect the sensor lead and plug for damage before assuming the sensor itself has failed
