The Worcester Bosch 87161423020 DHW NTC Thermistor is a genuine Worcester Bosch hot water temperature sensor. It measures the temperature of the domestic hot water and sends this information to the boiler’s control board, so the boiler can deliver hot water at the correct temperature.

NTC (Negative Temperature Coefficient) means the sensor’s resistance falls as the temperature rises. A faulty thermistor can cause hot water that is too hot or not hot enough, temperatures that go up and down, or boiler fault codes.
