A genuine Glow-worm part, this thermistor is designed for use in Eden, HXI, CXI, British Gas, C-CI and SXI 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.
Please always refer to the manufacturer’s instructions for the correct application. All parts should be fitted by a qualified plumber.
