Glow-worm Thermistor Thermometric Sensor 801722

This Genuine Glow-worm thermistor thermometric sensor (part 801722) is a replacement component designed to maintain reliable boiler performance and support correct operation of compatible heating and hot water systems. Manufactured under the Glow-worm/ Vaillant Group Spares umbrella, it is intended to restore and sustain efficiency and longevity in compatible models, backed by the Glow-worm manufacturer’s guarantee. The sensor plays a key role in controlling heat output by providing resistance data to the boiler’s control system, enabling appropriate adjustments as temperatures change.

The thermistor functions by decreasing circuit resistance as the surrounding temperature rises, feeding this information to the boiler’s printed control board. This enables the system to determine whether to increase or decrease heat, helping to maintain stable operation. The part is designed for use in Glow-worm Eden, HXI, CXI, SXI and CI boilers, and is compatible with HXI, SXI, CXi and CI models. As a genuine Glow-worm product, it comes with the manufacturer’s guarantee.
