Frequently Asked Questions

Q: What is an NTC 10K temperature sensor and what does it do in a boiler?

A: An NTC (Negative Temperature Coefficient) 10K temperature sensor is an electronic component that measures the water temperature inside your boiler system. As the temperature changes, the sensor's electrical resistance changes in a predictable way, allowing the boiler's control board to accurately regulate heating output and maintain safe, efficient operation.

Q: How do I know if this sensor is compatible with my gas wall-hung boiler?

A: This sensor is compatible with gas wall-hung boilers and water heating systems that use a standard NTC 10K thermistor probe. Check your boiler's service manual or the existing sensor's resistance rating (10K Ω) to confirm compatibility before ordering. When in doubt, consult a qualified heating engineer.

Q: Can I install this temperature sensor myself?

A: A confident DIY homeowner can replace this sensor, but it is strongly recommended to power off and fully cool the boiler before beginning. If you are unfamiliar with gas appliance servicing or your local regulations require a certified technician for boiler work, please engage a qualified professional to carry out the replacement safely.

Q: What size is this NTC temperature sensor probe?

A: The sensor probe measures 1.85 inches (4.7 cm) in length, making it compact enough to fit neatly inside most standard gas wall-hung boiler housings. Please verify the required size against your boiler's specifications before purchasing.
