Frequently Asked Questions

Q: What type of boiler is this NTC 10K temperature sensor compatible with?

A: This NTC 10K temperature sensor probe is designed for gas wall-hung boilers and hot water heating systems that use a standard 10K ohm NTC thermistor as their water temperature input sensor. Always check your boiler's service manual to confirm the required sensor resistance value before purchasing.

Q: How do I know if my boiler's temperature sensor needs replacing?

A: Common signs of a failing temperature sensor include inaccurate temperature readings on the boiler display, frequent error codes related to water temperature, or the boiler cycling on and off unexpectedly. If your boiler's diagnostic system flags a sensor fault, replacing the NTC 10K probe is often the recommended first step.

Q: Is this sensor easy to install at home?

A: This sensor is a straightforward replacement part with color-coded leads (black and red) for easy identification. However, since it involves a gas heating appliance, installation should be carried out by a qualified heating engineer or technician in accordance with local safety regulations and your boiler manufacturer's guidelines.

Q: What does NTC 10K mean for a temperature sensor?

A: NTC stands for Negative Temperature Coefficient, meaning the sensor's electrical resistance decreases as temperature increases. "10K" refers to the sensor's resistance value of 10,000 ohms (10 kΩ) at a standard reference temperature (typically 25°C). This is one of the most common specifications used in residential gas boiler water heating systems.
