What it is

The Ferroli 39805620 is a 10K NTC wet sensor supplied as a pair. It is used in Ferroli gas boilers to measure water temperature and provide resistance feedback to the boiler's control board. This wet-type sensor is designed for direct contact with the water circuit.

Signs this part needs replacing

  • Boiler displays a sensor-related fault code
  • Inaccurate or fluctuating hot water temperature
  • Boiler short-cycling or failing to modulate correctly
  • Heating or hot water not reaching set temperature
  • Resistance reading outside the expected 10K NTC curve

Before you order

  • Confirm your boiler model against the fit list above
  • Check whether your boiler requires a wet or dry sensor
  • Verify the existing sensor part number and connection type
  • Note that this part is supplied as a pair
