Thermistor

Thermistors, or NTC sensors, measure water temperature in gas boilers and help control the heating cycle. We stock a wide range of replacement thermistors for popular boiler brands, including Worcester, Ideal, Baxi and Glowworm. Whether you need a DHW thermistor, a flow sensor or a heat exchanger probe, you will find it in this category. Our technical team checks the fitment of every part before it is listed, so you can order with confidence. In-stock orders placed by 4pm Mon–Fri (10:30am Sat) are despatched the same day. We offer 30-day returns on most items. If you are looking for an obsolete or hard-to-find thermistor, our Doncaster-based team can help source it. Visit our trade counter at Kirk Sandall Industrial Estate or call 01302 279234 for advice.
