A genuine Glow-worm part, this thermistor is designed for use in Sustain, Easicom, Energy, Home, Betacom, Essential and Ultimate boilers. The thermistor decreases circuit resistance in line with temperature increases. A boiler’s printed control board (PCB) sends a current to the thermistor, deciding whether a decrease or increase in heat is required by reading the relative resistance. Glowworm spares are manufacturer quality spare parts that can save you valuable time and money extending the life of your boiler.

Please always refer to the manufacturer’s instructions for the correct application. All parts should be fitted by a qualified plumber.
